[Tagging] Is power=generator like landuse=* or building=yes?

[Phil! Gold]

When people use power=generator, which is more common: tagging just the
building where the generator is housed, or tagging the entire facility
(including coal pile, gas tanks, offices, rail yard, etc.)?  Whichever one
you do, how do you mark the other one, if at all?
