I don’t want to test this right now, but some of my previous devices would just reboot after keeping the power button pressed for approx. 10-30 sec, overruling the need to use the on-screen shutdown menu - probably to be able to escape a frozen/broken system without waiting for the unremovable battery to run out. That could very well still be the case for some current devices out there.
