AFAIK there has not been a single incident of a cis-gender person being injured or damaged, either by themselves or someone else, because someone introduced a progressive theme in a video game...so if a developer might help someone find acceptance by representing them within a story, heavy handed as it may be, that may be forgiven, because it actually doesn't hurt anyone...
Well, neither do criticisms of misapplied allegory hurt anyone. I have no problems with art sending messages - in fact, I don't think art can avoid sending messages, so writers/artists/etc.. should take care not to send unintended ones rather than attempting to avoid them completely - but if an allegory isn't a natural fit in the story, it can legitimately be criticized.
As an example, there are some lesbians in position of power in DAI, and nobody mentions that as being unusual. Which of course, it isn't in Thedas since sexual orientation isn't such a controversial thing. That, too, sends a message, but it isn't heavy-handed. Celene and Briala are mentioned to have been lovers. Period. No extra "they're lesbian" point is being made. It's obvious enough and players don't need to be hit over the head with it. It's "Just tell the story and if that sends a message, nice." rather than "warp your story elements in order to send a message".
Counter-example: Krem. I think Bioware changed the Qun for that, and that I resent. It's one thing to create a world where that message can be sent convincingly in the first place, but quite another to change it at some point to make it so. If the writers refuse to be bound by what they've written earlier, there may come a point where plausible worldbuilding ceases to have any meaning.
