Liberties were already taken in regards to female viera as they're slightly different in regards to their lore and overall look compared to their FFXII counterparts.

It's almost as if some people don't actually care that much about the lore and they're just using it as an excuse to make it more difficult for male viera to be added to the game. Note how often the concerns come from posters who primarily play female characters and who rarely if ever hold female viera or female hrothgar to the same standard.

Would I like for male viera to have a proper introduction story and presence within the game world? Sure. Though let's not pretend as if there aren't already race/gender combinations that barely get more than a string of dialogue justifying their presence.

For me, the most important thing is that they're added at some point. I think gender locked playable races (or jobs) are exceptionally sleazy as a concept.
