That's true, however, if you can hit CTL-ALT-DEL, it's reasonable to
assume you have console access to the machine and can do one of the

1. Login and issue a reboot command.
2. Hit the reset button.
3. Power off the machine.

The idea of CTL-ALT-DEL sending a signal to init is attractive and since
everyone should be implementing some kind of physical security policy for
critial systems, some Joe Random User walking up and hitting the sequence
shouldn't be a problem.
