I don't think vim is meant to be an IDE. If you want an IDE, go get an IDE. If you want a text editor, vim works well. But vscode is unwieldy as a text editor, and vim is painful to contort into an IDE.
Obviously people have made things for VIM to be IDE like, some are cool to me, but completion-integrations-lang-servers always seemed so anti-vim to me. Make an HTTP request every key stroke to get suggestions? The. Latency.
The issue isn't with the fact people try to use it that way, it's that those who use vim are adamant it's the best option for doing so and berate the Other until they try.
