At least for the scoreboard, that one is no mystery. One of the loudest demands on these forums throughout all of '21 and '22 was that the scoreboard be removed. It was a contentious issue even then, but it sure leaned in the ‘anti-’ direction during the whole pre-launch period (e.g. this oldie ). I don’t blame FS for taking the middle road and not having it in base game but also allowing the mod to go ahead. In fact, it was probably the best choice given the intensity of the feedback they were getting at the time.
But it’s been a while and it has become incredibly rare to come across an anti-scoreboard opinion anymore, so perhaps now is the time to integrate it into the game. My only worry is that whatever they make won’t be as good as the slightly-tweaked Ovenproof scoreboard I currently use.
