This is the main reason why I came up with this refinement. For example, if I search for "ref:" at taginfo, there are *millions* of results. I believe this has implications in data management, although I'm by no means an expert on that matter.

As it stands, there is a possibility for namespace collision. That is theoretically a problem. An object might have two references, but we've made heritage references take the form ref:xxx=* so if the other ref is of the form ref=* there won't be a collision. But it's also possible that both schemes want to use ref:xxx. So adding heritage to the ref key fixes that remote possibility. As it stands, overpass queries would not be able to distinguish the right ref if an object has a heritage ref:xxx=yyy and a non-heritage ref:aaa=bbb. A remote possibility. Adding heritage to the ref key fixes it.
