</span>Right, I think in the Havana timeframe, things were very different. Part<br>
of the rationale for full parity was that applications would be written<br>
against nova-network, and smoothly transition to neutron. But with over<br>
90% neutron, assuming someone is writing to the nova-network API and not<br>
realizing it's the odd ball, I think is the wrong assumption. <br></blockquote><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
