Ah, I did the "silly" thing of looking on the RVI website at extension status (because I never know the order of things) and these two extensions were marked on there as being in the inception phase, so I incorrectly assumed that "public review" came before freeze. Freeze is the standard that we have been applying so far, but if ratification is imminent, and nothing has changed in the review period, then it seems sane to just pick the freeze point for the definition.
