I think this is dangerous thinking - the config you want depends so
hugely on your intended workload and available hardware that trying
any strong view of what an Openstack deployment should look like into
the deployment tool forever forces that deployment tool to be a minor,
niche product that *has* to be replaced by something more expressive
in order to be widely usable. The config you want for a primary hadoop
shop is totally different to what you'd want for primary web-host shop
is somewhat different to what you'd want for a public/generic cloud,
etc. Things like AZ support, neutron model, cinder back-end choice,
H/A model etc are dictated by scale and use-cases. If you only want
your config tool to deal with one deployment type, that tool becomes
pretty much irrelevant to the totality of the Openstack effort, and
should be replaced by something more layered/openminded.

This isn't to say we must boil the ocean right now and make everything
available, but rather that decisions should take the long view into
account.
