Many newcomers using your plugin will have a huge problem when using vanilla VIM. The same problem exist with Spacemacs, Spacevim or other weird things.

If someone don't want to use VIM modal editing why not to stay with Sublime/Atom/VSCode or any other editor? They also have very rich plugins ecosystem. Not mentioning that Sublime is like crazy fast...

To clarify it's not an attack on anyone. For instance evil mode in emacs is also a heart breaking plugin for me. Every editor is made for different workflow, why on earth mix them up? And in most cases it does not work very well.
