Inconsistent spreading_*_pussy / spreading_*_anus, and spread_pussy / spread_anus tags

spreading own pussy/spreading another's pussy imply spread pussy, but spreading own anus/spreading another's anus do not imply spread anus. Also, spread anus implies anus, but spread pussy does not imply pussy.
The spread pussy wiki states that the pussy must be visible for the tag to apply, but the spread anus wiki doesn't mention this same requirement.
Because spreading own pussy/spreading another's pussy currently imply spread pussy, it's currently impossible to adhere to the spread pussy wiki page's rule of the pussy needing to be visible, as adding spreading own pussy to images like post #11160309 adds spread pussy automatically.
If the current spread pussy requirements are followed, then we'd need to unimply spreading own pussy/spreading another's pussy -> spread pussy. But this would mean 17,000+ images would need to be gardened to remove improperly added spread pussy tags from images like post #11160309.
Instead, I think we should just remove the visibility requirement from the spread pussy wiki page, as the current spreading_*_pussy implications have already 'poisioned' this pool of tags, then do the following to align the behavior of all related tags:
remove implication spread_anus -> anus
imply spreading_own_anus -> anus
imply spreading_another's_anus -> anus

Edit: I've submitted a BUR to fix/align the behavior of these tags: BUR #57758

I was adding missing spreading own pussy and spreading another's pussy tags to spread pussy images and noticed that the first two tags both imply the third tag (which makes sense), but spreading own anus and spreading another's anus do not imply spread anus. Also, spread anus implies anus, but spread pussy doesn't imply pussy. Is this intended or should a BUR be made?

Agreed there’s some inconsistencies here. The spread pussy wiki says not to use it when there’s clothes blocking the pussy from sight, however the implications you mentioned make that distinction impossible. Consequently, if spreading own pussy and spreading another's pussy imply spread pussy, then spread pussy can’t imply pussy. It’s also why tags like puffy nipples don’t imply nipples; covered nipples exists too. I would be against an implication from spreading own anus to spread anus because of images like post #10935497.

You're exactly right. I've gone through a lot of exampes of characters attempting to spread their own pussy, but their pussy isn't actually spread, like in post #10968448 - I think spreading own pussy needs to not imply spread pussy (since it's an action, not a visible feature), and same with spreading another's pussy. I'll go back through all of the spread pussy images again if / after a BUR is created to unimply the spreading_* tags from spread pussy.

After sitting on this overnight, I'm thinking it'd best to keep the current behavior of spreading_own_pussy & spreading_another's_pussy implying spread_pussy, and instead, have spreading own anus & spreading another's anus imply -> spread_anus to align their behavior with the *_pussy tags, remove implication spread anus -> anus, then remove the spread pussy wiki page's requirement for the pussy to be visible. That would align the usage of all tags, and seems like the most intuitive solution to me. I created a BUR for these changes here if anyone would like to vote: BUR #57758

Would love to hear everyone else's thoughts. Should spread pussy and spread anus require the pussy/anus be visible, or should they act as the parent tags for spreading_*_pussy / spreading_*_anus? ? If they're not kept as parent tags, how should we deal with the thousands of images like post #11160309 that have already been tagged with spread pussy due to spreading own pussy and spreading another's pussy implying spread pussy?
