lisp-free emacs to me is like tomato-free ketchup? I mean, the main reason to use an editor with such arcane keybindings is the way you can live-edit the running editor?

So for me personally there's no demand. But still, if it scratches your personal itch, there are most probably others who would like that itch scratched. It might also because I rarely have to use windows these days and in linux there's not much 'setup' in using normal lispy emacs.

Also, for me , electron based editors have too much input latency.

You might be right! For those who love Emacs for its Lisp environment, this editor is probably not useful at all.

I just made this for people like me, who instinctively press C-f instead of the right arrow key, but just want to start typing immediately without any setup.

As for the input latency, it might indeed be slower than native editors like Notepad. However, by using a custom Piece Table and virtual rendering, I personally don't feel the delay on a modern PC, and I am very satisfied with the responsiveness for my daily use.
