About canon/non canon whatever.
Star Wars has a different "canon policy" from Star Trek. "Word of God" for Star Wars is that anything in the movies trumps anything else, then the official novels of the movie. But unless it's directly contradicted by either of the above, books by other authors with the official seal of the company do have *some* canon (or official) status. Even computer games are somewhere around that level (they have published a table of "canon levels" which I forgot).
Paramount (and possibly Roddenberry before he croaked), however have stated publicly that NOTHING except the TV shows and the movies are canon. Not novels, comic books, anything. Even the "animated show" isn't canon. If an episode of the TNG show, for instance says that some technobabble may make phasers turn people into Tribbles, it is canon. If the cartoon did it, it's just silly and should be disregarded.
Now, canon has zero meaning outside of the body that controls the franchise. All it means is that "the author/publisher considers that it happened or not". Star Trek novels: never happened (except within the novel's own "alternate universe"). Just like some Batman or Superman Comics (elseworlds, all-stars or something?) never happened within the "official" continuities.
Going by this, it's highly unlikely that player-created content is going to be considered canon on Star Trek for future movies or shows. Within the game universe, sure, why not.
