What? I've been using X since 1992, and I've never considered ctrl-alt-*
to be reserved for X. Nor have I ever met anyone who's espoused such
a position. What's more, on other popular OSes, ctrl-alt-* is a very
common shortcut key sequence, so I can't imagine any new users expecting
it to do magic violence to your system either.

(What's more, on my Maltron keyboard, ctrl, alt, and backspace are *next
to each other* in a line, quite easy to accidentally strike simultaneously.
Of course this really *is* a minority keyboard, so I'm not saying that
defaults should change because of it: I'm just glad they did.)
