Completely agreed. I don't think there's a great way to support most Rust devs in a stable Emacs release besides treating Rust like any other language, deferring to normal environment settings, and letting individuals, their configs, and their outside libraries cross the thrash gap to fix defvars, envvars, and other settings as needed.

This, however, also sounds like a great enabler to me. Rust devs would gain the option of easily matching the change velocity in their elisp config rather than through env vars, which would probably improve the case of Windows users that Pankaj brought up earlier.

Apologies to the participants for my jumping all over this thread. I'm absolutely in support of improving the new Rust dev experience if Emacs can do it without painting itself into a corner. Rust has a lot of paint. :)

Cheers,
Ian
