I agree that it could have been implemented and written a bit better, there are certainly issues, but unfortunately, at this point, IMO, it's too late already.
I mean, for example, Astarion epilogues with a mindflayer Tav are still a complete and utter mess. Spawn also feels utterly neglected, compared to AA, he also has absolutely no reaction to being kidnapped hy his siblings. These are much more pressing matters, IMO.
So at this point, I would much rather Larian fix their glaring huge bugs and inconsistencies before walking away from the game, instead of wasting time on something that at least somewhat works already.
