High hopes for Rust: where are we?

Since the compilation times are the first (and maybe the only one) issue I'm having with Rust,

I would like to know if something has been done, especially about:

Putting it all together - Compile times

Between incremental linking, a parallel frontend, macro expansion caching, release mode-macros, and precompiled binaries, I’m positive we could cut Rust compile times by 90% or more. None of these steps are impossible, but they need dedicated engineers backed by a substantial amount of funding.
