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.
