I don't think it applies. Vi's key idea is a composable text editing language, and it's transferrable between editors, with a few quirks but mostly intact. (although there are new editors that iterate on this idea, and they have their own, better designed, but incompatible text editing languages). Emacs' key idea is a composable environment, which translates poorly to non-LISP languages and other programmable editors due to their more rigid design. It's really an operating system with a non-conventional architecture.
