For plugins maybe, but coming up with a thoughtful set of key bindings takes work. If everything is reconfigurable, like with Emacs, I don’t see the harm in giving users something to start with.
Evil-mode is an example of what I am advocating here.
Imagine if evil-mode could start with a blank slate. Wouldn't that be easier?
The problem is that every package is designed to integrate with regular default-Emacs. If you are using evil-mode, that means every package presents its own edge case.
