You said "The ingress qos minium bandwith rules was only added in 
neutron" - did you mean a release rather than "neutron", as in a release 
newer than newton, presumably much newer?

Isn't this all admin-only by default in neutron since newton? So how do 
we know there will be "a lot" of existing cases? Do we know of any 
public openstack clouds that enable this for their users? If not, I'm 
guessing by "a lot" maybe you mean a lot of telco private cloud 
openstack deployments that just have a single MANO tenant?
