I haven't written LSP so I'll reserve the opinion at that. What I understood about emacs is that it doesn't have a concept of a project so I don't see how it can form dependencies that are more sophisticated. But maybe I don't understand something about that. I can totally write these sort of plugins for any IDE I worked with. Notice that all of these capabilities are symbols of a bygone time where you stuck everything into an editor. There's no motivation for a plugin developer to do these sort of things. Instead we have plugins like Lightrun, TabNine/Copilot, etc. Stuff that's actually useful for development. JetBrains (and some other IDEs) have a builtin file manager, terminal, etc. These make some sense for development.
