Is there a better way to tag this? Individual nodes for helicopters are marked, but the platform as a whole is tagged aeroway=aerodrome, which is someone misleading and renders an airplane icon. It seems there are only three instances of aerodrome=helipad:

I'll add this for now, but would it make more sense to mark the platform as a whole as aeroway=helipad?
