you said manor is an example, and I agree, but we have still to look at all object types individually, because for a historic=castle only 58% have a building tag, and looking closer we might eventually find that some of them could be extended as well. A castle (defensive one, this tag is very generic compared to manor) typically is composed of several buildings, open space, defensive walls and more, so having a combination with building seems less likely unless the mapper has selected the main building and ignored the others. Similarly I could imagine a manor to be bigger than a single building, e.g. comprising ancillary buildings, a garden or similar.
