[openstack-dev] [nova][limits] Does ANYONE at all use the quota class functionality in Nova?

Nova's API has the ability to create "quota classes", which are 
basically limits for a set of resource types. There is something called 
the "default quota class" which corresponds to the limits in the 
CONF.quota section. Quota classes are basically templates of limits to 
be applied if the calling project doesn't have any stored 
project-specific limits.

Has anyone ever created a quota class that is different from "default"?

I'd like to propose deprecating this API and getting rid of this 
functionality since it conflicts with the new Keystone /limits endpoint, 
is highly coupled with RAX's turnstile middleware and I can't seem to 
find anyone who has ever used it. Deprecating this API and functionality 
would make the transition to a saner quota management system much easier 
and straightforward.

Also, I'm apparently blocked now from the operators ML so could someone 
please forward this there?
