You linked empty positions as they are on real board. Thus, any small
changes on the empty positions will change the graph. Or, most likely, a
little change in a colored group may change the links to the empty
positions. These make me feel the representation is not topological
invariant.

Where were the comments from others? I missed them?
Subgraphs don't have names for empty positions, why should they?
What does this not respect that you would like respected?
