I'm really not comfortable with that idea, it seems like most of the users would be abusing it - one of the biggest issues is always getting people to understand that their driver may be used in other systems with the supplies mapped differently. If you were going to do something along those lines you'd need to do something that enumerated all the supply properties on the device.
