If you mean we shouldn't fix the V2 API to report Neutron quotas (rather that "we shouldn't change the V2 api to remove network quotas) then I disagree  - currently the V2 API contains information on network quotas, and can be used on systems configured for either nova-network or Neutron.   It should provide the same consistent information regardless of the network backend configured - so it's a bug that the V2 API doesn't provide network quotas when using neutron.

I know we want to deprecate the V2 API but it will still be around for a while - and in the meantime if people want to put the effort into working on bug fixes then that should still be allowed.
