I am not sure if I will like BG3. What you describe would mean I would defeinitely not like BG3.
Which part specifically wouldn't you like, Wormerine? What is off-putting about it?
Don't know about Wormarine, but for me, just about everything is off-putting. I play video games largely to NOT experience other human interaction, so much so, that I don't even care about MP or co-op modes in games.
When I want to experience human interaction, I have usually found it most satisfying through direct communication rather than vicarious shared experiences.
I also greatly like the lack of human interaction in single player games. It is relaxing. Multi-Player is a different feel, more like a party, hence LAN-party, and I enjoy those if I am co-operating with a team which is competing against another team.
The commentary aspect of the game, if it is introduced, could be a solo experience too. It would be akin to watching TV. (Many people are turning away from TV these days, for many reasons.) Streaming is popular enough for Larian to build support for it into the game. I think that commentary needs to be included with that.
Think about why some people would point their browser at a BGIII stream. It is "the same story", so why would they repeatedly watch BGIII streams? What would the audience be getting from it? How would the views help BGIII itself?
