I think we, at the very least, need a clear proposal how to resolve the
scalability issue around OldSnapshotTimeMapLock in 9.6.  Personally I
think we shouldn't release with such a large regression due to a
performance oriented feature; but if we do, we need to be confident that
we can easily resolve it for 9.7. In contrast to the spinlock issue I
don't see an easy way unfortunately. Without such a plan it seems too
likely to go unfixed for a long time otherwise.

Sounds good, especially around the regression with the feature disabled.
