It will take a lot of effort to slowly carefully reduce the error/bug surface and add proper parallelism constructs, that are easy to use for any package author.
Emacs is my editor/IDE of choice and consider myself power-user. However, I'm no expert in its internals or elisp. I understand that things are built with single-thread execution in mind over decades. However, I think things still can be more async, where you can offload heavy stuff to separate thread and stream results. E.g. Magit status doesn't need to block my entire editor. It can run what it needs to do in separate thread, send the results back to main thread just for rendering when its ready. Same with say consult-ripgrep / consult-find-file / find-file-in-project etc -- doens't need to wait for it in main thread and block the render / event handling until entire result set is ready (e.g. in this case things can be streamed). As in maybe there is a way around to make this much better by message passing/streaming instead of sharing state itself?
I love Emacs, but it really just fails to be effective for me when I work on monorepos and even more so, when I'm on tramp.
