If we can reuse one of modifiers like that, yeah. But there's a limited 
amount of prefix modifiers we can use and, again, it's not very 
discoverable.

That's not to say that you couldn't integrate the new commands to be 
delegated to with certain prefix values, like vc-root-diff does.

To be clear, I'm not wild about adding new commands, but if we add 
functionality, it must go somewhere.

Windows are jumping, it can be annoying. And in the end it might 
redistribute heights between windows in a top-bottom split.
