I'm not so sure I agree that there has been no feedback.

The nova SRU fixed *38* bugs. Our usual SRU verification process is
mostly cumbersome red tape compared to the review process that the stable
updates team for OpenStack used to get these fixes in. 8 of the 38 bugs
were verified.

The lack of participation in the SRU process shouldn't be seen as an
indication that people are not interested in updated OpenStack, but
rather that people aren't interested in re-verifying the bugs they've
already verified during the normal update process they use upstream.

The whole point of these types of exceptions is that we get more fixes
shipped to users when an upstream project takes sufficient steps to
reduce regression potential. OpenStack has a fantastic process in place
for that, and I think we should feel comfortable trusting that process
given the amount of influence Ubuntu developers had in creating it and
continue to have in maintaining it.
