The more important thing is that people are still bothering Larian on basically every platform to fix Karlach's problem, and honestly I'd prefer them cooking up something new and exciting rather than just have Dammon jump in and fix everything.
Well the good news is there are like was it three or just two other avenues of investigation that are basically SCREAMING "we know about that infernal engine/iron stuff" that just don't have any quest attachment to Karlach's whole thing because her Act 3 quest is just mysteriously missing even though things clearly meant for it are not. The skeleton already exists to do more than just hand Dammon that last piece of infernal metal that otherwise has no use in the game, so it's easy to hope that they add meat onto those bones and either earn the tragedy through a meaningful quest that ends in failure, or opens up a more hopeful ending result that does not involve being stuck going back to Avernus.
