Conversely, LSP is quite limited in comparison to what can be done with a real IDE integration in JetBrains product suite, so it is not so clear cut. See this post for some details: https://matklad.github.io/2023/10/12/lsp-could-have-been-bet...
It's a bit odd for the parent commenter to say "Weird post" and implying that having an editor specific feature would somehow make having an LSP that works for everyone be any less interesting.
