Part of the reason I added areaSymbol to parking areas is that mapnik _does_ render icons on parking areas. After reading some of this thread I see it has a collision detection system which is the reason you haven't seen duplicate icons there (as long as you placed the node close enough to where mapnik placed the automatic one).

If I were working on an area and saw a parking node inside a parking area I'd definitely remove the node, moving tags as needed.

If anybody decides to automatically clean up all the data they'll of course have to handle those cases.
