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. :)
