I'm pretty sure you can gay in previous DA games before Inquisition. That said I generally agree that devs shouldn't be forced to add stuff end to try to please everyone but I also believe that everyone has the right to express their opinion on the matter regardless.
Wasn't there a [censored] storm fairly recently over not being a female in Assassins Creed of Dishonored? Anyways I agreed that we shouldn't force a devs to throw something into a game if it doesn't fit. It does no one any favors at that point. However I do feel like those who want it should ask for it in the future because it's not happening at this point.
Also you read the codex? I just clicked on them for the little bit of XP.
