What I'm learning by reading this thread over again is that there is a lot of confusion about relations in the context I'm interested in. Group or site, whether one or the other will render or, more importantly for me at least, is whether the object will be findable in a Nominatim search. I would hate like hell to have tagged such an object and then not be able to locate it. I don't care which method gets the nod on this list but in the end I want those features to be findable.
