“Brown-out detection” is a pretty standard feature even in cheap microcontrollers (which, granted, are much more straightforward about their power). Don’t know how it holds up in an adversarial situation—not that well, probably. (You’re ultimately powering the comparators and voltage references off the same power supply, would be the first possible class of problems.)
