i get that it's likely a remnant of the past from back when mizuki's gender identity was more ambiguous, but i gotta say as someone who is transgender it does suck to see the non-binary tag still being slapped onto this pairing (i get that its there alongside the transgender tag, but i think it being there at all takes away from the fact that she is, in canon, transgender and not non-binary (i also get that it's never technically been confirmed outright, but it's literally the only way her story in-game makes sense and it doesn't have to be said out loud for it to be canon)).

Mizuki's story is such an unambiguous portrayal of a transgender character and to see her being labeled as non-binary because of project sekais translation team choosing to dance around her identity and degender her constantly sucks

Real.
I also often feel unsettled for labeling her as non-binary. Maybe it's finally time for dust to settle.

100% agree. Non-binary is trans, of course, but the people who were calling her NB weren't calling her NB because they actually saw her as transfem, but as a way to distance her from being a girl. I don't play it, but even as an outsider, it's clear that she's a trans girl character victim of the usual transmisogyny.
