Which would take us right back to the beginning of the thread :).

The current number of multipolygon relations in the database isn't  
that big. A couple of thousand, it looks like. I'll try making a  
script that applies inner/outer roles heuristically, based on polygon  
area or similar, and that handles the tags sensibly. If that works  
out well, we could switch over without creating a new relation.

But I don't mind either way.
