or whether mailpony needs similar implications
Agreed. Done.
Why? I guess technically not every mare is a pony (can be a horse for example), but do you think we’ll get non-ponies tagged “mailmare”?
I think I was expecting to see more images of Gabby here, but - yeah, the vast majority (granted, it’s a very small set in any case) is pony. And given that:
mailpony +> pony
Added the implication:
mailmare +> mare, mailpony, pony
Fun fact: Derpi even has a mailgriffon tag.
Agreed. Ah! Found one:
mailgriffon +> griffon
There! Our tags are now officially more set up than Derpi’s (where the set of cases is 1).
