>In all seriousness, folks, I'm bringing up points about the proposed API
because I see the current mess of Neutron integration with Nova, I see that
nova-network has been "undeprecated" due to continuing lack of parity and
HA concerns in Neutron, and I want things to be better, not worse.

Again, I haven't seen any evidence that ongoing development of this new API
is preventing any of the parity work from happening. Nobody is advocating
that the parity work be delayed because of this. We are all aware of the
threats the TC has put forth with regard to demoting Neutron to incubation
unless the parity demands are met. If you want ongoing development to stop,
this should be a clear requirement and it should be evenly applied to all
work (LBaaS separation, ML2 enhancements, any third party drivers, etc).
