Nope. Again, context matters here. I never use emacs in a terminal; all editting of files on remote systems is done in a local X11 emacs over ssh. And this is not because of circumstance but because making that choice opens up more doors. I can have keybindings not just on C-z but ones that aren't representable in the terminal at all (e.g. I like to put end/beginning-of-buffer on C-. and C-,)

Would I submit my choices as good defaults for new emacs users? Hell no. But they remain good choices nonetheless. That's the essence of my point, not the minutiae.
