The thing about linux is that ime you can just implement this individually across all (most) the apps I use. I have vim-like binds for mpv, my pdf reader, terminal emulator/terminal file manager, image viewer, and of course my window manager.

The ones where I don't are the ones where it would be too complex to be taken care of by an external app. A DAW would need its own core implementation of modes for example, same with something like Krita and in that case it would probably not even be advisable.
