Maybe it is a part of Otsutsuki clan culture for children to absorb their parents to gain their power, even though we haven`t seen many examples of it, we can guess. Perhaps this is their own twisted way of making sure that the young surpasses the old and if you think about it, there is some fridge horror in there, maybe the reason we haven`t seen Otsutsuki clan members in larger group numbers is because they attack each other for their chakra when they are not directly related( as a way of not killing their parents). The boruto movie possibly confirms it with the reveal that kaguya created the zetsu army to ward off momo and co. because they would cannibalize her. Also this is my first post on the naruto wiki.
