I don't understand the purpose. Would those new keymaps be for temporary,
experimental, bindings, to be later moved to a better position? Or would
they be meant to be eventually used by default?

I personally like to have C-z free. I use it when I need to pass keypresses
to applications without caring about Emacs missing them. For instance my
Screen prefix key is C-z. Suspend-frame is bound to C-x C-z (which makes
sense to me with the other C-x bindings). So I would immediately undo such
a change in my configuration.

More importantly, C-z suspending the terminal application is a common
binding. One could argue that we have enough trouble with non-standard
bindings in Emacs not to add more now.

Maybe this behaviour could be preserved in non-GUI interfaces and the
(hypothetical) C-z key reserved for commands which only make sense in a
graphical setting? I cannot think of a single such command at the moment,
though.

I just tried <f2>-s to see what it is about, now my Emacs is frozen (100%
CPU). As far as I'm concerned this key can (and will) die tomorrow. :)
