That said, I bet there is already some example of a canon character that has been outed in a TrekLit story.
Hawk was gay. Worf's replacement, from First Contact. I'm fuzzy on the details but I think it was supposed to even be mentioned in the movies, but it was changed before filming (or maybe even filmed and cut). Probably for the best as the guy was killed pretty badly and that would have been the wrong message.
I was always hoping Kes would come out.
Hawk being gay was mostly cut because it served no purpose to the story, plus how do you add into the movie without it sounding silly?
"Where's luitenant Hawk, your gay conn-officer?"
"Sadly, our gay conn-officer was killed."
It's a bit odd like that.
Throughout my 30 years of life, I've had several gay and lesbian friends, and to me being gay is no issue. And I think that for the Federation in the 24th century, the same thing applies; it's no longer a big deal.
So, for the writers, it's very difficult to write a story about a character discovering that he/she is homosexual and writing intense drama around it.
Honoustly, if (for example) Nog would turn out to be gay, the changes of someone from his inner circle reacting with disgust or hatred (something I've come to understand is the biggest fear for gay and lesbian people these days), sounds very stupid. So you have to first bring them into a situation where the character is surrounded by people who hate homosexuality, and THEN having that person coming out, so to say.
Story-wise, all of that would be almost soapy, and personally, I believe that's the biggest reason TrekLit writers have never made a big deal about gay or lesbian characters, and just write them like that. Like with Sean Hawk and Keru. They just were a gay couple, and it was the most normal thing in the world.
And, again personally, I found that very satisfying, since it very much implied that that is a future we are heading towards.
