Yes, I saw it. And semi-anthro is a subset of anthro
This might be where some of your confusion is. Derpibooru distinguishes anthro from semi-anthro as 2 completely separate classifications.
Use this for anthros without actual human features. For anthros with them, use
anthro instead.
.
And description for
anthro states:
For anthros without actual human features, use
semi-anthro instead.
.
The arm hoof tag is specifically for anthro only. It has nothing to do with shoulders or arms, but rather indicates where there are hooves instead of hands. And since all semi-anthro character animals with hooves already have them, the added distinction would be pointless.
Semi-anthro is simple and rather straightforward; if the character is the animal in every way while standing upright “naturally” (i.e. not
bipedal), it is semi-anthro. And you can absolutely have visible shoulders on semi-anthro and even bipedal.
Anthro is where it starts getting a little complicated and requires a number of subset tags to distinguish them (such as arm hoof)… and I actually know people who are absolutely disgusted by / attracted to one type of anthro, but not another.
