Me neither. This is really my first time digging into subgraph. It makes
sense (to me) that each vertex/edge should have only one property, but I can
see reasons for localizing properties as well. If both are needed, I can
create specializations of property_map that select local/global lookup
strategies. Would that be acceptable?
