This reverts commits a04ccf6 et al. in the back branches only. There was some disagreement already over whether to back-patch 157f873, on the grounds that it is the sort of behavioral change that we don't like to back-patch. Furthermore, it now looks like the logic needs some more work, which we don't have time for before the upcoming 14.4 release. Revert for now, and perhaps reconsider later.
