Hi, RMS, hope you are doing well!

Hi everyone in the emacs-devel list!

Today, in the GNU Emacs Spanish chat group at Telegram, came to my
attention that there is a project forking Emacs and putting Rust 
in it.

The project started by replacing xdisp.c with 4,000 lines of Rust 
and so
far, it works (per the videos linked in its GitHub repo)

https://github.com/eval-exec/neomacs?tab=readme-ov-file

I'm in the process of building the binary and test neomacs.

Anyway, I was thinking, if Linux has Rust in its source code, 
could GNU
Emacs have it, too? What would be the requirements for such 
experiment
to even be considered? Other than `rustc` be Free Software.
