If marked dialogues can be implemented by having a check box to toggle it on or off, I guess it depends on how you want to play your game. Sometimes, having an extra dialogue option (especially for Githyanki) would have been nice, but I also thought that how conversations could lead to unexpected outcomes was rather a strength of BG3 rather than a weakness. I hope I wasn't a save scrummer, but the quicksave button was handy if I really misunderstood something.
