What are you talking about? Every Rust project I see seems to have 5 dependencies that do some simple thing that should be in the standard library, or at least in some centrally-audited monolibrary of utilities.
Perhaps you're referring to things like regex and rand (each of which is itself multiple crates for the purpose of code organization), which are all first-party crates provided by the Rust organization itself, simply shipped and versioned separately from the standard library? If you trust the Rust organization enough to install and run the provided toolchain binaries on your machine, then you trust them enough to depend upon the dozens of crates that are provided under the umbrella of the Rust project.
Not GP but I feel like there's a continual process of the stdlib adding some new functionality to make one such crate redundant (e.g. is-terminal in 1.70), but it isn't done yet.
Yep, that's why I was asking. I'd be very interested to hear of more candidates for uplifting into std.
I guess saying "every project" has 5 dependencies might be somewhat hyperbolic (or at least domain specific) but it would be interesting to know the kinds of things they're talking about that haven't yet been uplifted.
