I love day and night cycle, but it's really up to Larian if they have enough time and resources to add this aspect in the game. I feel like it could open up a can of worms if the settlements act the same way during the day as during the night, so they need to make different routine. It's not easy and potentially adding bugs. With that being said, if it's added, it would be nice, but if not, then I would understand since it's not something that could implement over night.
