9.3 Wish: Support esriTopologyFace

Fantom Planet says ESRI is looking for ArcGIS 9.3 suggestions.

Anyone remember REGIONPOLYCOUNT from workstation ARC/INFO?

As far as I can tell there is no equivalent in desktop. I’ve had to write code that walks around the edges in a topology to build closed “faces”, then count up the parents of the faces. This is very useful in analyzing featureclasses containing overlapping polygons.
It looks like ESRI was planning on doing this at one time, take a look at the constants, but sadly there are only 2 classes that implement ITopologyElement. Would be nice if there were a class called TopologyFace.
