What you say is true, but I guess I didn't make my point clearly enough. If a building contains multiple addresses, it is wrong to put one address on the building trace. It should, instead, be put on some smaller object. Usually that's a node, placed within the building outline, but it also be a `building:part` trace, if you want.

In any case I've fixed it now, and the address that had been wrongly tagged on the whole building has been moved to a node.
