I would assume someone (a moderator or Community Representative) is responsible for this. If there isn't one, there should be one appointed. But seeing as how DoS only improved from player feedback over time, I would imagine the same would happen with BG3.
I started the pinned topic (which I am admittedly rather behind schedule with updating: RL got in the way) and when I suggested it, the response was pretty much that while another summary of player feedback is welcome, it is already being noted. I have little more information than that myself, but will pass it on if anything is forthcoming.
