How come? I don't know anything in say, pycharm, that can't be done with a LSP server and plugins. But that's probably because I don't know enough so I'm curious about what limitations an LSP would involve!
Refactorings are one example where LSP can’t match IntelliJ. A language server also takes far more skill and effort to implement than the equivalent IntelliJ plugin, where much of the heavy lifting is done by the IntelliJ framework. And you still need at least a lightweight plugin for each supported editor. That’s why a language server isn’t necessarily the best place to start but hard to avoid in the long run.
