I think many of the criticisms and suggestions made regarding changes outside of those things are futile without that context, and without the context that they legally can't do much beyond that because they're no longer contracted with wotc.
While I have no insight into Larian's contract with WotC, I am highly doubtful that they wouldn't be in control of BG3. They did start working on potential follow up content, so it doesn't seem WorC would prevent them from doing more in ther world if they wished to do. While there was no doubt some business agreement, I doubt Larian was on WotC's payroll. BG3 would never be worked on for so long if WotC was one footing the bill.
I think they were working on the follow up content before they ended their partnership with wotc and handed over the rights to the companions. I would love some clarity regarding what they're allowed to do now. But I don't see how they would be able to make changes or additions to a world and to characters that are part of the IP they no longer hold rights to. It's their game and I imagine they're able to make changes that don't significantly alter the IP, and wotc will allow that to maintain a good relationship with them. But I think there's a reason they announced the decision not to add new narrative content for the companions or world at the same time they announced ending the partnership with wotc.
