Spacemacs has holy-mode so it’s not just to make it emacs feel like vim. It’s curated and managed like a distribution, and in my opinion makes emacs much more accessible.

I’d say in both cases, once you have editor support for syntax highlighting, refactoring, autocomplete/intellisense, live/interactive error reporting, etc. you’ve stepped out of the realm of text editing and squarely into IDE territory.

A fully loaded Spacemacs install (and by the looks of it, LunarVim) is not Eclipse or VS with reSharper, but they compete and are well beyond a simple text editing.
