I think the homogeneity is a big problem. It does not take advantage of the local site to optimise for transit accessibility (through greater vertical density at transit nodes), energy efficiency (optimising for passive energy use through building geometry) and liveability (integration of mixed-use commercial functions for example). The design of these communities is a really cheap but effective way to upgrade the communities along these objectives and it's constrained here by the rigidity of using one housing type.
