As a general rule of thumb, if the original creator didn't write it, or at least approve it, it has never happened. If the creator of the source material didn't officially make two characters a couple, they are not a couple. "Ship Tease," as they call it, also does not necessarily mean they are a couple. If something is implied, you need to acknowledge that it is implied, and not explicitly stated.
I dislike it when anyone seriously supports any non-canon pairing. It doesn't matter what your "one true pairing" is. It only matters what the original creator intended. As much as you like your yuri or yaoi fan pairings, they will likely not happen and should never be taken seriously or as fact unless they do.
However, in a game where there are multiple romantic interests, such as Mass Effect or Katawa Shoujo, this debate is a bit more legitimate, but there is no such thing as "one true pairing" in those circumstances. If you like to romance Liara, that's your preference. It's is not necessarily the way that it is meant to be. There is no ideal pairing, no matter what you think.
