But then we'll end up with non-tagged ways. From the OSM data design perspective its not going to be very practical for someone to determine whether the way is not tagged because it belongs to a certain relation or because it was forgotten. And don't forget that a relation could be anything. not just "polygon-with-hole", so you would have to understand the semantics of all types of relations. Also, since AFAIK osmxapi currently does not support relations, renderers which use data collected from it would have to ignore these untagged ways completely.
