Why the key should not be used on relations?
Why did you write that the building=* key should not be used on relations ? There almost one million buildings mapped as multipolygon relations!
This question comes up often. We defined an area as as a closed way with appropriate associated tags or using a multipolygon relation creating an area from one of more ways. This means that should not be used on relations means should not be used on relations (except multipolygon relations). See also previous discussion:
