Interesting, but I think we need a key that doesn't have any meaning in the
context where a region might be active. Maybe that means we need a key that
isn't yet bound; dunno.

Imagine that you want to use the key for one of the uses described above (e.g.
clear the region or exit the minibuffer or a recursive edit). If the region is
active in the current buffer (e.g. the minibuffer in the latter cases), then
would you be doing ESC ESC ESC ESC ESC ESC? And what if you wanted one of those
behaviors but did not also want to deactivate the region?

Too complicated, IMO. But worth thinking about.
