Duplication was the only reason. Retroactive delegation is a real pain --
you have to wipe the data, delegate the property, and then rewrite all the
data (to the property you're delegating from). Actually, probably the right
thing to do would be to deprecate the /sports/sports_facility/capacity
property, and copy all the data to the new venue type.

What do folks think about that?
