When it comes to WotC, best not to focus on what's "canon" and what isn't, because it contradicts itself, and the written works especially contradict the video games. Even with BG3's popularity, I have zero faith that what WotC ultimately takes from it for "canon" will line up with the game canon at all, especially as the years pass. The stuff WotC has "canonized" from the old games makes it look like they learned about the games from playing telephone . . . even when writers of new content also worked on those games. It's whatever they think will sell, not what's logical and consistent.
