There is no such thing as "Vim as an extension." I've tried so many different Vim extensions in different editors, IDEs, web browsers, etc. None of them are without some glaring deficiencies, big and tiny annoyances. With perhaps the only exception - Evil mode in Emacs feels like a built-in thing; you forget that it's an afterthought, an extension. It works as if it was designed to have it from the get-go. Yet, I agree, if you must use VSCode, IntelliJ, Sublime, Emacs, etc. - you don't have to unlearn your vim skills. What's great about vimming - it's like riding a bike, you learn it once, you can do it anywhere.
