Ctrl-Alt-Backspace is not an SAK and never has been, because a malicious program could simply remap the keyboard such that Ctrl-Alt-Backspace didn't terminate, then grab and play around with turning your display off and on to simulate a server restart.

I think the point being made here is that there would be NO WAY to override this, including key remapping (well,there's nothing we can do about someone performing hardware hacks on your keyboard :-)). Or, probably preferably, you could override those keys individually but when pressed together they always trigger that particular event regardless of remapping.

Obviously, the choice of CTRL, ALT, and BACKSPACE for this purpose is sub-optimal for many reasons, not least of which is that they are often remapped.
