For the record, what was clarified was that the agreement that the allocation_request blob that had been previously agreed to as an opaque blob had been compromised by some last-minute hacks to get migrations working before the Pike deadline. As a result of this change, it was now necessary to add versioning to these allocation_request objects, because now Nova or any other service could be altering them as they saw fit. I still think that this is a terrible design, but I will bow to the pressure to go along with accommodating the change to the previous design.
