Comment 3 for bug 1936408

I am of the opinion this is not a bug. Lowering the quota for a resource below what exists should be allowed, it will just make sure that the new quota is used in future calls. For example, if it generates an error how is the user to change the value without deleting resources?

I will agree that components have different responses here, so if Neutron (and Octavia) is somehow the only one behaving differently then I could see allowing it via a config value, but changing it without that will break the API contract.

Also, Octavia behaves similarly to Neutron - the quota can be lowered without an error.
