> A large stdlib solves the problems the language is focused on
That's part of it, but it also solves the problem of vetting. When I use a Go stdlib I don't have to personally spend time to vet it like it do when looking at a crate or npm package.
In general, Go & Rust packages on github are high quality to begin with, but there is still a pronounced difference between OS packages and what is approved to be part of the language's own stdlib.
It's nice to know thousands of different companies already found the issues for me or objected to them in reviews before the library was published.
