Weirdly there was just an article on how 5e's devs approach canon, WotC's stance on canon for streams, video games, novels, and the like is apparently "treat it like a home game." They specifically mention that this allows RA Salvatore's novels to go off in different directions from the RPG's lore.
https://dnd.wizards.com/dndstudioblog/dnd-canonYeah, this was brought to my attention on another forum few days ago (not during this same discussion, for the record, but it was a thread about BG3).
People didn't seem particularly happy about it in general. Many seemed to think it was WotC being once again wishy-washy and coward about stating openly what it considered current canon, for the record.
