I guess we can deprecate the entire quota-class API directly.
I had a spec proposed to deprecate the os-quota-class-sets API [1] but it
was abandoned since we discussed it at the Pike PTG and decided we would
just leave it alone until Nova was getting limits information from
Keystone [2].
FWIW - in addition to merging the conceptual document [0], Sean recently
proposed the limits interface [1] for the keystone bits.

I think the reason we probably missed this API was because of the really
roundabout way that the information is provided in the response. It calls
the quota engine driver [3] to get the class quotas. For the DB driver if
nothing is overridden then nothing comes back here [4]. And the resources
in the quota driver have a default property which is based on the config
options [5]. So we'll return quotas on floating_ips and other proxy
resources simply because of how abstract this all is.
To fix it, the os-quota-class-sets API would have to maintain a blacklist
of resources to exclude from the response, like what we do for limits
[6].
So yeah, I guess we'd need a new spec and microversion for this.
