Vim is relevant because it is not always possible to customize it. Think of hardened servers or containers. Also, it's an editor of last resort on most Unix systems. It's worth discussing whether nano should take this place instead. Much more tricky are applications that have hardcoded hotkeys, or who listen to an unholy mix of keys and scancodes. Uncommon nowadays (many games are not great at this), but still sucks if it happens.
