If they decide to not do male viera for preference/budget reasons, of course they're still going to come up with an in-universe explanation for why they're not playable. Even if Miqo'te men are meant to be rare, they're still native to Eorzea. Viera men are both rare within their homeland, and not native to anywhere we can go. So that's even more justification for why we see Miqo'te but no male Viera.

Besides, Yoshi-P understandably does not read the English forums or reddit, so he probably remains blissfully unaware of the vocal minority that go insane over male viera (in-game, almost all discussion I've seen is people making fun of Balmung players who don't get their bunnyboys). Hrothgar are a perfectly valid allocation of resources over another gender of rabbits.
