This logically makes a lot of sense. It gives EQG humans a tag of their own just like every other species on the site while solidifying the distinction between standard and EQG humans. I’m not sure if there’s a mechanism in place to retag that many images though.

How I understand it, one of the uses of the “part of a set” tag is to indicate images from the same creator that are thematically associated but not chronologically related (ie. comics).
I created the “sugar morning’s smiling ponies” tag specifically for that set of images. They are all variations on a single base and were advertised as such. In addition, a few months ago, me and some others here agreed that the tags “ych result” and “part of a set” should be used when multiple images were produced from a single YCH base. While most of the smiling pony pictures don’t have either tag, I believe most of them should (though if any of those images by Sugar Morning of their own accord without any YCH sale, those may not warrant a “ych result” tag, but I digress).
The tag “whistle blossom’s teacup ponies” was created by the artist herself, proving that these images are meant to be related and don’t just coincidentally share a theme. Therefore, I think it’s fair that these images are called a set. Even if the artist didn’t clearly link the images in text, I think the images are similar enough to be called a set regardless.
