Rust will already allow you to have multiple versions of transitive dependencies.

This needs to be screamed from the hill tops!

To be honest, this is the kind of thing that would be great to highlight immediately on https://github.com/rust-lang/cargo or http://doc.crates.io/guide.html.

I go to those pages and I am given 0 information on how the thing actually works.

Cargo's docs need a bunch of work, it's true. I have so much to do :(

Which I guess is normal since it does not create any dependency cycle. A new version might as well be thought as a completely different package (of perhaps similar functionality).
