sigh. and it's wrong too.
"Current default for X servers as shipped in various distributions is to not
enable the traditional Ctrl-Alt-Backspace key combination to kill the X
server."

The server has no say in it. in fact, the server _enables_ zapping by
default (see 737b49199a05299486064e6e762cf2a2f6f95be6). It's just that the
standard keymap does not include the zapping symbol and that can be added
through the appropriate options.
You can disable zapping in the server in which case having the symbol in
your keymap has no effect.
