But we don't have dynamic inheritance of permissions, so this "ownership" relationship is only instantaneously useful, at the moment that the Item is created. Is there really any need to preserve it? Apparently it doesn't really have anything to do with ownership, but only with having a handy place to keep defaults. I don't think Item ownership should be clarified; I think it should be abolished.

That's a good question. Someday when we have a revised data model that lets us do this in a more natural way, we'll be blessed; in the meantime, however, people do use mapping and it might be worth some small effort to make it less hairy. (Thinking back to tinkering with directories directly in FILES-11B filesystems and how I'd hoped to never again see links done that way. Having one apparently undistinguished link actually be different from all the others makes things remarkably ugly.) -- Mark H.
