I'm curious, what's the significance of using radios here? What's the correlation between having a radio and supporting that interaction? It just feels weird to me to think of a majority of hardware companies going "Well, this device has a radio, so I guess we need to add power+volume down as a shutoff trigger".
Not disputing what you said is true, just curious of the origins!
In most radio contexts it's used for doing a debug log... in case of a hard lock. If you do it on an Android device (depending on settings), it generates an error log and memory dump then cuts power to the chip. It's an old carry-over from radio testing (Former RF Validation Engineer here)
