FWIW, I think you actually don't have much reason to complain. This work
has probably gotten more attention in total than any other recent
patch. Certainly, by far, more than any other in the 9.5 cycle.
So far I've not seen a single version that could be considered 'ready
for committer'. Even if there's points to be resolved you can make one
(presumably yours) solution ready.
