How would you have a user-configurable switch that physically disconnects things? The mechanism for that sounds complex. I'm not a hardware person, but I imagine you'd need to route the traces for each possible component to the switch and then have like a dip switch panel to control which behaviors are controlled by the switch. Either that or a software-controlled equivalent to a dip switch panel that can only be configured in the bootloader, otherwise the software-controlled physical disconnect would be no safer than a software disconnect.

Im not a hardware person either, but ex the button physically turns off the canera, and software polls for camera power and can respond

Since these things are almost certainly digital devices, just having a switch that cuts power to them could work.

As soon as it is sufficiently complex, it becomes a "trust me bro" switch.
