The bulk update request #12367 has been rejected.
We make an exception to not tag personification on franchises that are entirely centered around personifications (such as Kemono Friends or Umamusume) to avoid flooding the tag, however creature and personification is made up of pictures where both the personification and the original animal/creature are present, so imo we should make an exception to the exception, because the act of personification is self-evident in these pictures. It's reasonable to expect these pictures when searching personification.
There's a case to be made for when it's actually humanizations instead of personifications, but there's no results so far in creature_and_personification humanization. There are some under humanization dual_persona, but they haven't been tagged with this tag, and we've discussed implicating humanization to personification before because of how close and often mistaken these two tags are, so I don't think it should be a stopper for this implication.
