I think having this would allow users with almost-homogeous hardware use
TripleO. If someone already has precisely homogenous hardware, they
won't notice a difference.
So i'm +1 for this idea. The condition should be that it's easy to
implement, because imho it's something that will get dropped when
support for fully heterogenous hardware is added.
