Well if the poly flow is so important then just use a poly modeler, where the toolset is all about pulling and pushing vertex.

Hoping that a nurbs package like MoI will output full quad sub-d ready mesh is just science fiction :P.

The problem with MoI meshing is that sometimes, the result is so close to a "perfect" topology , it gives the illusion that with some extra work (from Michael) the model can be used as a subd cage.
