Seems like they want to soften the impact of shadowlands on the lore without retconning it. Idk, that's a weird hill to die on. Shadowlands has created so many issues with the lore that trying to fix them takes way more time and effort than straight up making the expansion non canon.
Also, i can't trust danuser because he doesn't seem to have a clear design in mind. Hearing him trying to give an explanation to his own writing was kinda sad tbh. I truly wish he'd step away from his position.
