I suspect that would result in having to regularly remove *_girl tags from animal boys because of people trying to tag the ears and tails.
You're correct, aliasing might be a bad idea after all. Probably just a remove with very aggressive nuking whenever they resurface then. It's always the same users creating them anyway.
Also, what about hypothetical cases of an animal tail being visible, but the gender (or species) of the owner can't be confirmed?
Let's be realistic, how many of these cases are there actually? I guess we could be forced to create a hyena_other tag or something, but how often do you see the tail or ears with the character being completely androgynous and unknown? I can rather see those posts being tagged with 1girl + androgynous than 1other.
The bigger issue is that you'd have to do an OR search to be able to find all results for certain ears, with, say, ~hyena_boy ~hyena_girl, but already barely anybody's searching for hyena ears. I added the statistics for *_boy tags, and there were only 35 queries above 50 searches per week. The vast majority is just one or two searches.
