This effectively already exists. The Xbox One SOC apparently monitors its own voltage and shuts down / doesn't function if it falls out of spec [1] as part of a totally OTT suite of anti-engineer techniques.
As an aside, I hate all of this. If someone made an open console, I'd buy it in a second. I realise that's probably my computer running linux next to me, but still...
Almost all microcontrollers have a feature like that - chiefly because at power-on the voltage rises gradually, and if it started running before there was a high enough voltage for it to run correctly you get a bunch of reliability issues.
