@Themble @TheMatrix Just to reiterate what's already been said on the auto reboot 72 hour default value. Auto reboot only kicks in after the phone has not been successfully unlocked for the set amount of time. In practice, almost nobody is going to leave their phone locked for 3 days straight without ever unlocking it once. If you somehow only check your phone only every 4 days, you can adjust the auto reboot timer or turn it off completely.
So, while this will realistically affect almost no one's regular usage, it will be very useful for putting all of your data back at rest to protect it in cases where your phone is stolen/seized or anything like that. It is actually a significant security improvement to the defaults of the OS.
