Fundamentally, I feel that any argument along the line of "this is a D&D game and thus players really should be able to make use of all of their party during conversations" is telling the devs what their vision should be. This is just my opinion, but I generally prefer sticking to what Larian stated as their vision, and pointing things in the game that don't work with their vision.
That's a thing to which I agree a lot. Devs have worked all their life to reach the point where they can design games as they like, and thats their moment to shine now. That said, even with the best intentions, everyone can make mistakes and being critical, in a constructive way, is always important.
