Since this is a from-scratch implementation, there's not much support from the language side to begin with. Except for some build system details that may have been made less annoying, I don't think much has changed.

Ehhhh yes and no, you're mostly correct. 2021 is currently the shelf year for the latest edition of Rust.

However rust versions everything, so even if you have a new compiler that removed support for something, you can still pull the old toolchains and build legacy codebases (like this one).

My Rust OS not only pins the edition (which is the default anyway with `cargo init`) but also uses a toolchain file to pin the date of the nightly build I want contributors to build with.

Rust tooling is really fantastic in this regard.

I chuckled a little, after all, GCC isn't versioned and there's no companies out there still using GCC 4 or whatever kind of suffering they prefer.

That wasn't my point at all, if you read the rest of the comment. I think it was clear I was referring to the ability pin and fetch specific versions of the toolchain when necessary, directly from Rust's tooling.
