I think you missed the point of my post. The value of Vim/Emacs isn't the modal editing or key chords. It's the community and architecture, which you lose if you're still using JB with a frankenport of Vim on top. In fact, I think what you're suggesting is the worst of both worlds - a reimplementation of Vim on top of an already resource hungry and complicated IDE that's supposed to let you do things with a mouse. So you're left guessing whether something from real Vim will be the same in your Vim, plus you now have two competing environments for ways to do things, and you have to wait for JB to implement features that (neo)vim have already implemented, without supporting the opens source communities that did the work in the first place.
You also lose the killer feature of Vim, which is being able to work over an SSH connection on any sort of device, even those that don't have a GUI.
