Comment (by Lars Aksel Opsahl):

 The main problem, as I understand it, is low vertex density for some edges
 then. In Simple Features, we have to change the density for the entire
 surface, which in turn affects the neighbouring surfaces. In Topology,
 since we only do this for individual edges, it should only affect the
 surfaces connected to and sharing that edge. We may also encounter
 exceptions if adding extra vertices causes an edge to cross another edge.
 What if we had a method like SetTopologyDensity(name toponame, float8
 density, geometry bbox)? Setting the correct density value should ensure
 that the problem is solved within a single feature context.
