and I replied:

1. No they're not. There are apps where you are supposed to hit 
ctrl-alt-delete, but accidentally hit backspace.. all your data is lost, 
and that's a far more important bug to fix than allowing a convenient way 
to kill X.
2. Then set 'Option "DontZap" "no"' in your ServerFlags
3. This has been discussed on xorg at lists.freedesktop.org numerous times, 
and the default was changed for xserver 1.6 & master on Oct 08 I think. 
Check the archives if you like... So, every distro that doesn't change the 
default will have this behaviour. I'm pretty sure that Fedora will not 
change it, and know for a fact that Debian won't.

And if you need to kill a session that's b0rked, you can just hit the 
reset/power button..
