This seems analogous to esp32 deep sleep. In this mode the co processor can monitor gpio pins on the device to wake up or even control some parts of the device… very useful for battery powered devices… makes total sense apple and probably all smart phones have a similar multi chip architecture to mange the device power and sensors… it does suck that the side effect of this could be used for evil and that even when we use the power off features it doesn’t turn completely off… I do miss real on off toggle switches that actually break the copper connection between the chips and the current…
