On the performance/stability of Elisp front, I just heard about remacs, which is a fork that's starting by porting all the C to Rust: https://github.com/remacs/remacs

Still in early stages, but I think that's one to keep an eye on.

I'd be much more interested in one of the CL rewrites, which could (1) run all of the elisp as efficient compiled Common Lisp, and (2) extend the customizability ot the deepest layers of Emacs.

Unfortunately, most seem to be relatively dead from what I've seen.

The rust re-write is not intended to bring performance benefits. Currently the Rust version is a massive downgrade in performance relative to the C nativecomp branch.

Most recent change is 7 months ago. I would not hold my breath.
