I agree with this.
We can't let these two regressions enter a release, so we have two
real chices:
1. Merge both fixes to 1.53 or
2. Revert the 'ar/run-command-hook' topic merge.
Hmph, at this early point in the late release cycle before -rc1
(yes, rc0 is scheduled for this morning, but that is not really a
release candidate that counts as anything), it is tempting to take
#2, actually. I just do not know how much damage such a revert
would cause to the tree. I'll experiment after I finish cutting the
-rc0 preview release.
