In 2021, the flag was updated by Valentino Vecchietti to include intersex people:

This addition is fascinating to me, because it so clearly reveals one of the Progress Flag's main issues, and rather than solving it, it contributed to the problem. The Progress Flag aims to highlight trans and BIPOC experiences, but when it is used as a replacement for the original rainbow, that automatically excludes anyone else. This soon turns into a competition of who is the "most oppressed" and deserving of a space on the main flag, which is altogether an unproductive discussion to have, only serving to further divide the queer community. This flag proposed that intersex people were one these "most oppressed" groups and added them, making the question: “why aren't [insert minority identity] group of people on the flag?”, a reasonable one to ask. (Ohio Flag Meme) Intersex is also an interesting choice, because, although some intersex people do identify as being queer, not all of them consider intersex to be a queer identity. It also somehow makes it uglier?!?! This is genuinely so confusing to me, because I get the intention of the Progress Flag, and I get how the creator came to the design that it is, but this addition makes absolutely no sense, and furthermore, lots of people seem to have adopted it? I think it is because it is seen as the “most inclusive” and people just don't question that.

I am probably being unreasonably harsh on this flag. It is by no means the worst I have seen and overall it is fine I guess, but it definitely shouldn't be the main flag that people use.
