Comment (by simonpj):

 CAFFY

 I rather agree.  But the same is true for `patError` etc, not just
 `absentError`.  I've opened a new ticket #15113.

 So if that was fixed, again this patch (or part of it) becomes a patch
 we'd want to revert.  But perhaps not all of it?  I'm not even sure any
 more :-(.
