No argument here.  I agree that it's an optimization and you know what 
they say about premature optimization. :-)

I do wonder whether the ongoing discussion about where container support 
should live in OpenStack is relevant to this as well.  Or would we not 
intend to manage the TripleO containers using OpenStack?  If we _do_ 
then that is going to be a dependency too - we won't want to commit to 
using containers until OpenStack as a whole has decided how we're going 
to support them.
