100%. I recently got rid of my lsp-booster and similar kludges because the builtin language server client (eglot) is now fast enough without it, even on large projects.

And if you want AI integration at your choice and control, agent-shell (and chatgpt-shell, which is LLM-agnostic despite the name) are great packages. They’re totally hackable with elisp like you’d expect, which I personally haven’t done a ton with, because I use AI pretty sparingly, but I imagine the crowd here could come up with plenty of ideas for how to program your editor and your agent interface together.
