Only harm I could see if someone grabs their phone to make emergency call and it's rebooting or locked and in their sleepy state, have trouble unlocking it.

However, I do think 12 hour "Phone hasn't been unlocked, reboot it" seems logical security feature to add.

You never need to unlock an iPhone to make an emergency call (if you mean 911 versus urgently needing to call some other number).
