It doesn't *have* to be in the backend, but currently it is. But for 
various reasons it's more convenient to have such hotkeys in the 
backend: not all backends offer the same features, so not all hotkeys 
make sense for them; not all backends even *have* hotkeys (dreamcast 
has no keyboard normally, right?); and if the frontends had to handle 
this, we'd have to make sure that all event loops in all frontends 
handle all the possible hotkeys.

OTOH, I see no real gain by not handling those in the backend...

To speak in RFC language: It's not a "SHOULD", it's a "MAY". "Backends 
MAY treat certain key combinations in a special fashion."
