Ctrl-Command-Power does an immediate reboot. Loses any unsaved documents. Doesn't shut down cleanly so potentially damages the filesystem. No "are you sure?". That's great: they thought the feature of "damage your computer" was so useful they should make a keyboard shortcut for it.
It's one key away from Alt-Command-Power which I use all the time to put the computer to sleep. So the feature is not only convenient, it's very "discoverable". I certainly discovered it yesterday.
Windows laptops solve the problem by making you hold down the power button for 5 seconds, to prevent you from doing it accidentally.
WTF Apple. That’s just insane.
