What are the advantages to replacing the C implementation of Emacs to a Rust based one? Especially in terms of performance, I'm not seeing it, C is generally faster than Rust, so all Rust could provide is better safety no? What needs to be made faster is ELisp, the parts of Emacs not implemented in C basically. Is remacs addressing that as well?
