Having potential and being something are sadly very different things.. but I agree, a lot of the improvements this game needs to be more than a simple cheese-feast like DOS2 are very easy to implement and on top of that contrary to Larian's features tested for balance.

Willingness is the big issue here. If they really wanted they could have corrected already a lot of things because I serisouly doubt the code for AI action prioritisation is that hard to adjust once you go back to the action economy of D&D (which is mostly like a simple variable value change from using bonus actions to use full actions). But we will see. If it doesn't come in the next two updates than its most probably because Larian doesn't want to go back to the proper rules.

I honestly hope they will make the changes. I want this game to be a success not just because I paid the full price for it, but because I want to see Larian succeed. Still I think they have a lot of deep rooted design issues with their games where they fall short of expectations with little room for improvement as they stick by their philosophies from DOS2. BG3 should have been an attempt to do things differently and not constantly fall back to crutches from DOS when it comes to world design, encounter design and companions. As long as they are not willing to try something new there isn't much growth left.
