Hello everyone,
I just found out that the "ambiguous" part in "ambigous_on_[species]" tags - such as ambiguous_on_feral, ambiguous_on_human, ambiguous_on_humanoid - refers to and implies ambiguous_gender. It would be more logical to me if "ambiguous" would rather refer to and imply ambiguous_species because [feral]], human, humanoid, etc. are categories for species, not gender.
On the other hand, "ambiguous_gender" has already all the "ambiguous/[gender]" tags - such as male/ambiguous, female/ambiguous, intersex/ambiguous, ambiguous/ambiguous, etc. Those help to narrow down and specify searches containing characters with ambiguous gender, while there is not much I know of to search for ambiguous species.I personally would change the "ambigous_on_[species]" to refer to ambigous species rather than ambiguous gender.
Otherwise we could also come up with two coexisting standards, my initial suggestion would be anything refering to ambiguous gender should use a slash, such as "ambiguous/humanoid" and anything refering to ambiguous species should use "_on_" such as "ambiguous_on_humanoid".What is your opinion?And thank you for your attention.
