Is this one of the ways it's not sufficient? If so, can you link some example posts? Thanks
Images like those are a good example of what I mean. Those are clearly equine penises, but do they belong to ferals or anthros? It's ambiguous. Semi-anthro is sometimes used for ambiguous, in-between cases, but it can't be used here because it's not as though their body-style is in between feral and anthro, but rather, their bodies simply aren't shown.
