The exact same arguments could apply to C-c being "replaced" by C-x C-c.
There is a big difference in that C-c is already used by Emacs for
other things, one is for users, and the second is for local
keybindings in modes. Changing that would break quite a bit of
things.
I meant when C-c was chosen, I wasn't suggesting to change things now.
But if C-x C-c for C-c was never too confusing, C-x C-z for C-z should be fine too.
In any case, C-z can display a message guiding the user to the proper key sequence. And one could argue that C-c could show such a message too(without breaking anything).
C-z z or similar for suspend with a message seems like a good
compromise.
I agree in general, with a preference for C-z C-z. But if C-z becomes a prefix key, C-z C-z (or even C-z z) will have the same "prime" status as C-c C-c today.
If C-z is purely for users with the exception of binding to suspend-frame, it should not be a problem, as users can always override it they don't care about tty suspend.
