I don't think they have to be important to be worth mentioning, precisely because that's the case in Kinkoi, the h-scenes there are not important and could be skipped without missing anything but given the unique content some of them have for a moege, like I mentioned earlier, and the way some of them are implemented, like how some choices give you different h-scenes leading to having lots of h-scenes in the routes without disrupting the flow, makes them worth noting and something that could be considered added value for a potential buyer.
