It's easy to be cynical because, yes, both the problems and solutions seem dead obvious in hindsight. But for a long time (and maybe even still), a hacker creed was "move fast and break things."
It's great that there's so much momentum in fixing the glaring problems with supply chain systems like npm, but I'm concerned that we're entering a new era of security-related problems caused in large part by agentic development.
I'm not just talking about Mythos/Glasswing surfacing vulnerabilities in pretty much everything it touches; I think the way we're developing software, pulling in dependencies, and potentially losing human thought modeling of complex systems is going to lead to a lot of hacked together software and infrastructure that humans won't fully understand.

He certainly popularized it (maybe coined it), but I've seen a lot of organizations and developers repeat that mantra.
Even without the specific words, look to product teams debating tradeoffs of going to market vs. waiting for better security controls. They're pushing for faster product release every time, at pretty much every org.
I actually wonder if somebody used a fake identity to set up an account with a warehousing/shipment fulfillment company that stocks things and ships them, then set up the appropriate EDI pipeline to send shipping orders to it... What would be the results if a decently budgeted adversary made something attractive looking that shipped malicious USB flash drives to anyone that requested one.
I know we're not in the era when a windows pc will happily run any autorun.inf and .EXE file found on an inserted flash drive or DVD anymore. But even so. What if it didn't even have any malicious data payload but somebody was shipping USB-A interface capacitor based usb killers?
What if it did have data on it and came with a slick color brochure walking people through how to run the binary, or in a linux or developer specific audience, how to 'sudo' the ELF binary that lives on its filesystem?

Supply chain incidents suck and we need to do better. Personally for rust I’m a proponent of the foundation supporting a few core crates that go under the same audit procedure as the main rust language and give funding to the project to limit supply chain vulns. I don’t think the right answer is to remove systems like crates or npm. Crate and npm are a boon for many developers.
Crates has also been making efforts to include rust sec, but in addition to the above I would like the community to shy away from many small dependencies to a few larger ones just as tokio has
Yeah I’d agree that multiple crates under one project is basically the same as 1 large crate. The real problem is how many people you’re trusting and it’s all coming from the same person.
Honest question. Commons, Guava, Spring, and more seem to take this approach successfully (as in, the drawbacks are outweighed by the benefits in convenience, quality, and security) in Java. Are benefits in binary size really worth that complexity?
And before someone says “just have a better standard library”, think about why that is considered a solution here. Languages with a large and capable standard library remain more secure than the supply-chain fiascos on NPM because they have a) very large communities reviewing and participating in changes and b) have extremely regulated and careful release processes. Those things aren’t likely to be possible in most small community libraries.
That dead code might have "dead dependencies" - transitive dependencies of its own, that it pulls in even though they are not actually used in the parts of the crate you care about.
In the worst case, you can also have "undead code" - event handlers, hooks, background workers etc that the framework automatically registers and runs and that will do something at runtime, with all the credentials and data access of your application, but that have nothing to do with what you wanted to do. (Looking at you, Spring...)
All those things greatly increase the attack surface, I think even more than pulling in single-purpose library.
Why? It's the essence of "Simple Made Easy": you don't have other code to complect with. You have a smaller interface, focused on a singular goal. When a library has to work as a standalone project, it can't be accidentally entangled with other components of a larger project.
Smaller implementations are also easier to review against malware, because there are fewer places to hide. You don't have to guess how a component may interact with all the other parts of a large framework, because there aren't any.
There are also practical Rust-specific concerns. Fine-grained code reuse helps with compile times (a smaller component can be reused in more projects, and more crates increase build parallelism).
It makes testing easier. Rust doesn't have enough dynamic monkey-patching for mocking of objects, so testing of code buried deep in a monolith is tricky. Splitting code into small libraries surfaces interfaces that are easily testable in isolation.
It helps with semver. A semver-major upgrade of one large library that everyone uses requires everyone to upgrade the whole thing at the same time, which can stall like the Python 2-to-3 transition. Splitting a monolith into smaller components allows versioning them separately, so the stable parts stay stable, and the churning parts affect smaller subsets of users.
Contrary to what the article here presents, Rust does not have a culture of microlibraries like NPM does. The author and their LLM are cargo-culting a criticism of Rust made by people whose only experience is with the Node ecosystem. The Rust stdlib may not be especially "wide" compared to languages like Python, but it is quite deep, with the objective of making it so that you don't feel the need to publish single-purpose libraries which only exist to fix papercuts. Dozens of new APIs get added with every Rust release, which, occurring every six weeks, amounts to hundreds per year.
“Personally for rust I’m a proponent of the foundation supporting a few core crates that go under the same audit procedure as the main rust language and give funding to the project to limit supply chain vulns. I don’t think the right answer is to remove systems like crates or npm. Crate and npm are a boon for many developers.”
This is my solution. We get the quality of a std lib without forcing it in the std Lib and without extra maintaining cost for the team
One man's bloat is another man's batteries-included, I guess?
My argument would be that if a more featureful standard library could get Rust closer to the superior dependency culture of Go, it'd be worth it. As-is, Rust dependency trees are just wild.
The rust team is already stretched pretty thin. A larger library is going to put more pressure on them. These libraries are already maintained and used. The rust project should just directly, fund, Shepard and guarantee a level of quality for the packages. The foundation has started some of this with the maintainers fund. No need to force it all into the std lib. Go has experienced breaking issues with changes in the crypto library causing churn in the ecosystem.
It's hard to have zero deps - I put many hours into one to have no required deps in the end but it was not easy, and writing declarative macros to do anything complex takes work (and a proc macro often means a minimum of two crates). Both of the crates it requires are part of the same project, however.
One of my other crates (getaddrinfo) requires windows-sys and libc which would be challenging to get rid of.
Indeed, I'm all for maximizing the amount of modules in the standard library. It's pretty obvious to me that Python thrives because of, not despite of, its standard library, "dead batteries" and all.
However, don't make the mistake of thinking that Rust has a small standard library. Read any Rust release and you'll see dozens of new APIs added with every single one. I'm tempted to paste the entire list of stabilized APIs from the most recent release for emphasis, but rather than making this comment three dozen lines longer, just look for yourself: https://blog.rust-lang.org/2026/04/16/Rust-1.95.0/#stabilize...
An extra tier of standard library which can make breaking changes, perhaps. Rust's stability guarantee for std means cryptography really shouldn't go in there, since sometimes algorithms & protocols get broken (DES, MD5, SHA1, etc.) and need to be removable. Without breaking changes you get stuck with security vulnerabilities, if not from cryptography then from other poorly-designed APIs.
A ton of the most popular crates on crates.io are already first-party crates provided by the Rust organization itself. This is often overlooked when people are wringing their hands about Rust crate graphs. Looking at the top 10 list of most-downloaded crates on the front page of crates.io, the only one not either from the Rust organization or from a Rust core maintainer is the base64 crate.

Many small crates published by large, trustworthy projects are fine and preferable to one large crate that "does everything".

do we really need both npm and nmp though
and pnpm
nah, remove NPM, nothing good comes out of that.
Move high value crates into the standard library?
Please no, that’s a terrible outcome.
What else would you suggest that also does not have terrible outcomes. The situation as is, is untenable.
As I said above
“Personally for rust I’m a proponent of the foundation supporting a few core crates that go under the same audit procedure as the main rust language and give funding to the project to limit supply chain vulns. I don’t think the right answer is to remove systems like crates or npm. Crate and npm are a boon for many developers.”
This is my solution. We get the quality of a std lib without forcing it in the std Lib and without extra maintaining cost for the team
This bloats the std library and forces lots more work and stress on the rust dev team. Not to mention it’ll add more churn to the std lib.
One man's bloat is another man's batteries-included, I guess?
My argument would be that if a more featureful standard library could get Rust closer to the superior dependency culture of Go, it'd be worth it. As-is, Rust dependency trees are just wild.

No need to force it all into the std lib. Go has experienced breaking issues with changes in the crypto library causing churn in the ecosystem.
Maybe give crates a gold star if they have no external dependencies?
That's not at all a bad idea, imo. And a silver star for crates which only depend on gold star crates...
It's hard to have zero deps - I put many hours into one to have no required deps in the end but it was not easy, and writing declarative macros to do anything complex takes work (and a proc macro often means a minimum of two crates). Both of the crates it requires are part of the same project, however.
One of my other crates (getaddrinfo) requires windows-sys and libc which would be challenging to get rid of.
I like the idea of low deps but zero is tough

In particular, most recently the aforementioned release stabilized the cfg_select! macro for convenient conditional compilation, which obviates the popular cfg_if crate: https://doc.rust-lang.org/stable/std/macro.cfg_select.html
