Comment (by Leo):

 I understand that this ticket isn't crucial to the 1.2 release (even
 though it fixes functionality that was changed in 1.2) but it would be
 really fantastic if it got addressed/landed early in the 1.3 cycle. It
 would be incredibly frustrating to do a third version of this patch if
 there were significant DB layer changes as part of 1.3.
