Just being able to attach an attribute that said "this is a power net,
use a larger trace" would be very handy--- and would have saved me
screwing up a board or two where I accidentally put down a signal-sized
trace instead...

Seems like since PCB already gets device attribute information for
footprints, etc. (at least indirectly), perhaps the mechanism it needs
to get net attribute information is already there?
