> The difference is that in another language the build step is delegated to someone else who has packaged the code

Fedora packages a large number of Rust libraries, just as you describe. Nothing prevents you from using the packaged libraries if you prefer them.

Nothing except, in no particular order: 1) only having one version of crates 2) mismatched features 3) new transitive dependencies that can be introduced at any time without any warning 4) only supporting one version of rust 5) packages being noarch and basically glorified distro-wide vendoring—so their build.rs code is still run on your machine at cargo build time

Same as any other library provided by the distribution in any other language.

Not in packaged Rust libraries in Fedora, at least. Please read the aforementioned link.

Packages containing only source is a consequence of the Rust ABI still stabilizing, see: https://github.com/rust-lang/rust/pull/105586 After ABI stabilization, Rust libraries will be first class like any other language.
