It's not clear we will get this into Casablanca due to the impending code freeze. We were subject to a misunderstanding and the summer schedule unfortunately.
The benefits to this proposal basically to fix something now (when it's easier/cheaper) than to fix it later when there will be existing PNF instances, at least in test.
The changes are small, and they mimic how to interact with AAI for VNFs.
There is mail out to the various PTLs to see if this could be squeezed in, possibly with an exception to code freeze (i.e., this would come after the code freeze).
