Please do not do this, it throws fuel onto the interoperability file
we still have not put out.

One actual technical drawback to doing this is that none of the
OpenStack services can depend on any of those keys actually being
defined, so this is still effectively just a single-deployment
'extras' field, with the only advance being that all rows may have the
same set of keys, depending on how the configuration changes over

It may feel that way, but it really does not help at all.  From a
cloud consumer point of view (including tools developed and used by
deployers, possibly across multiple cloud deployments) this is no help
at all.
