Subject: Revert "Merge branch 'ar/run-command-hook'"

This reverts commit f406b8955295d01089ba2baf35eceadff2d11cae,
reversing changes made to 1627809eeff75e6ec936fc609e7be46d5eb2fa9e.

It seems to have caused a few regressions, two of the three known
ones we have proposed solutions for.  Let's give ourselves a bit
more room to maneuver during the pre-release freeze period and
restart once the 2.53 ships.
