Those are not per se release blockers. They are (perhaps important)
improvements to functionality. I don't know who is active and able to
review that part of the code; I'd look for authors of changes in the
surrounding code. The question here isn't so much what one would like
to see in this release, but evaluating whether the release is sound
and free of show-stopper problems. There will always be potentially
important changes and fixes to come.
