FWIW, what you've done here would dovetail into the all-in-one Heat undercloud installer effort too in that we could pretty much eliminate the use of instack to bootstrap os-collect-config altogether and just use these subpackages directly. Faster, better, leaner I think.

We've still got some refactoring to do to fully eliminate more of the os-*-config dependencies (os-apply-config, and os-net-config) but I think we are closing in on it.
