As I've said in one of those threads, we should decide whether we really want to keep these tags before creating any new implications. So it's probably best to revive forum #78699.

Well for now I'm doing the implications. Removing the tags later will be easier if the implications are already in place because then we'll know they all have pantyshot + position in place.
