> supports 14 of the kernel's 20-ish architectures

That's a lot better than I expected to be honest, I was thinking maybe Rust supported 6-7 architectures in total, but seems Rust already has pretty wide support. If you start considering all tiers, the scope of support seems enormous: https://doc.rust-lang.org/nightly/rustc/platform-support.htm...

They probably get a few for "free" from LLVM supporting them

    LLVM platform support is neither sufficient (rustc needs to be taught about the platform) not technically necessary (you could write a rustc backend that targets a platform that LLVM doesn't, like modifying cranelift or once the gcc backend reaches maturity).
