That's not an apple-to-apple comparison, since Rust is a low-level language, and also because `reqwest` builds on top of `tokio`, an async runtime, and `hyper`, which is also a HTTP server, not just a HTTP client. If you check `ureq`, a synchronous HTTP client, it only adds 43 packages. Still more, but much less.

And in Go I can build a production-ready HTTPS (not just HTTP) server with just the standard library and a few lines of code. (0 packages).

That Rust does not have standard implementations of commonly-used features (such as an async runtime) is problematic for supply chain security, since then everyone is pulling in dozens (or hundreds) of fragmented 3rd-party packages instead of working with a bulletproof standard library.
