Yes, that would be a way forward for 9.6 if we are not able to close blocking open items before beta1.  However, I think it would be bad if we miss some of the below listed important features like snapshot_too_old or atomic pin/unpin for 9.6.  Can we consider to postpone beta1, so that the patch authors get time to resolve blocking issues?  I think there could be a strong argument that it is just a waste of time if the situation doesn't improve much even after delay, but it seems we can rely on people involved in those patch sets to make a progress.
