Probably a pretty big job though... It also encourages *really* bad practice with error handling, and in general there are few use cases for optional regulators where there's not some other actions that need to be taken in the case where the supply isn't there (elimintating some operating points or features, reconfiguring power internally and so on). If we genuninely don't need to do anything special one wonders why we're trying to turn the power on in the first place.
