well, it isn't an exception that a building is something different than who occupies and uses it. I am not advocating overlapping ways, my suggestion is to use a multipolygon relation. I have changed my own mapping accordingly after I got aware that it is a better mapping style, but I used to add myself amenity and other stuff to the building outline, and I still do it sometimes in cases I think are not problematic (e.g. supermarkets), at least as long as this doesn't create ambiguities (i.e. there are so few tags that it doesn't matter). There are also other situations where it seems fortunate not to reuse the way for different features but to use a relation, e.g. fenced stuff (way with barrier=fence and relation for the polygon inscribed) or islands (way with natural=coastline and relation with place=island (or natural=island if you think that place should be reseved to human settlements)). cheers, Martin
