You two are confusing me even more. AFAICS, the hierarchical
properties don't seem to change whether exclusive is set or not. It
still ensures children can't have something parent doesn't allow and
exclusive applies to whether to share something with siblings, so I
don't think anything is broken hierarchy-wise. Am I missing
something? If so, please be explicit and elaborate where and how it's
broken.

Thanks.
