Its STD exists because Go is a language built around a "good enough" philosophy, and it gets painful once you leave that path.
Uh... yeah? That's true of basically all platforms, and anyone who says otherwise is selling something.

Still less painful than being zero-day'd by a supply chain attack.
The point is someone needs to curate those "deps". It's not about rolling your own, it's about pulling standard stuff from standard places where you have some hope that smart people have given thought to how to audit, test, package, integrate and maintain the "deps".
NPM and Cargo and PyPI all have this disease (to be fair NPM has it much worse) where it's expected that this is all just the job of some magical Original Author and it's not anyone's business to try to decide for middleware what they want to rely on. And that way lies surprising bugs, version hell, and eventually supply chain attacks.
The curation step is a critical piece of infrastructure: thing things like the Linux maintainer hierarchy, C++ Boost, Linux distro package systems, or in its original conception the Apache Foundation (though they've sort of lost the plot in recent years). You can pull from those sources, get lots of great software with attested (!) authorship, and be really quite certain (not 100%, but close) that something in the middle hasn't been sold to Chinese Intelligence.
But the Darwinian soup of Dueling Language Platforms all think they can short circuit that process (because they're in a mad evangelical rush to get more users) and still ship good stuff. They can't.
It’s not that unique though. I can say that Python and hell, even PHP have pretty complete but also well documented stdlib.
Java is meh tier but C# is also pretty good in this aspect.
It’s totally a choice for Rust not to have a real stdlib and actually I feel like that would maybe make Rust maybe the best language overall.
