Yeah... adding other patterns misses the point. It's a rainbow. It's a spectrum that covers everyone. It's not like one group owns a given stripe. As soon as a broad symbol becomes a collection of specifics, you wind up asking 'why this group, but not that group?,' and it's a whole thing.
You want a flag that explicitly supports trans people? We had that. It's... the trans flag. And also the rainbow flag, because y'all were already covered. You're even in the acronym.
i think the biggest issue with the progess pride flags are licensing issues. the original designer of the flag with 5 bars on the left published it under a license that retains copy right. i don't care that he's legally in the right, it's sort of a dick move considering the significance of such a flag.
