That sounds really neat. I spent a couple weeks trying to publish all my notes using org-mode, and it was pretty frustrating to find all these key bindings on the net that didn't actually work in my setup. A bare setup where you could opt-in to keybinding "packages" with a global way to see conflicts would be cool.
It's been a pet idea of mine for a while, but every time I have tried to implement it, I have gotten tripped up on some UX design decision, or some fundamental, but poorly documented, part of the codebase.
My dream is a doesn't-resemble-vim modal editor from scratch. When I want more functionally, I will give it an intentional home in my normal mode config.
