Does Cargo re-use dependencies today? Last time I tried to build medium-sized Rust projects, it pulled hundreds of dependencies each time, even the same ones. It took up too much space, and took too long to build.

Yes, and it always has. If you do a second build, it will not rebuild those dependencies again.

Rust supports multiple versions of the same dependency, so that may be what you observed.

Yeah, I believe it was that.
