Even saying "we're working on it due to the large amount of feedback about it, but no promises" would be better than silence imo.
Swen said that already re: Reactions in a prior PFH and everyone took it and ASSUMED that Larian was going to eventually deliver Solasta-like reaction system. Notice on this recent PFH, he was much more careful about the topic of Reactions and glossed right over giving another update and/or promise that the final system would look different than what we saw.
Honestly, some of the questions people are clamoring about actually have been answered somewhere. You're not getting a party of 6, RTWP, or a day/night cycle.
There's no benefit to them saying anything else. They can't stay in EA forever and Larian has a history of biting off more than they can chew with overpromising and underdelivering.
