Newhalf tag - Can not ambiguous things stay ambiguous?

This tag should be used if you can either visually confirm the character has no vagina or there is information that clearly supports that the character doesn't have one, such as the tags used in the source, the artist's commentary or indicators in the art itself that confirms the character is a newhalf. When in doubt use the futanari tag instead.

The newhalf wiki states this, but considering that information from the creator is often insufficiently provided, especially for AI-generated works, this does not seem appropriate.

I believe ambiguous things can stay ambiguous. Specifically, requirements for futanari can include feminine breasts as well as genitalia, and thereby encompass the definition of newhalf. Also, I don't understand why 1other can't be used for futanari.

AFAIK, this is because futanari is unpopular and it is a tag important for blacklisting. Futanari is the default tag. It's not newhalf unless you can tell it's a newhalf. I don't remember why futanari tags are used with 1girl. It makes sense though.

This might be off-topic, but that's why I said, “Can ambiguous things not stay ambiguous?”

If there were no difference in value between them, we would lose the motivation to distinguish. If we did not believe ourselves to be right and others to be wrong, we would lose the motivation to measure value.

I see no reason to differ from danbooru on this tag. Maybe we should alias newhalf to futa_without_pussy too. The latter is already tagged on 3 posts.
