For backporting purposes, would it make sense to apply this patch first,
then apply the other one which undoes this patch as part of its
simplifications?  Then, anyone trying to pick and choose patches to
backport can feel justified going with the smaller patch in isolation.

As for this patch itself, ACK, but whether to apply it depends on the
answer to the bigger question above.
