Ah I think I understand what you're suggesting now. This hypothetical switch is both a physical and software disconnect. Some features like the camera would be physically disconnected by the switch and therefore would not be user-configurable but then some other features (for example, GPS) could additionally be software disconnected at the same time.

That seems like a neat idea, but IMO I wouldn't trust the software-controlled half of it, so I'd end up only using the non-configurable physical portion of it.
