Well they are both confusing, and I'd prefer to focus on the common case without extra mandatory steps. Exposing optional endpoint sharing information seems more in line with where everything is going than making endpoint sharing a first class object. AFAIK a device with multiple endpoints where those endpoints are shared with other devices doesn't really exist/or is useful? Eg PASID has multiple RIDs by they are not shared.
