Doesn't matter. Their desire to stay on a ship with no hope or expansion and a place they've admitted they can't sterilize with their tech is a form of madness. Like it or not, they are getting off that ship. Forcing their kids to live their lives in a ship, never basking in a warm day on a real planet, never going where they want with ease, is utter madness. Plus like I said, sell the ship, it's theirs after all, turn it into tourism or a museum piece and give them a ship of equal size these days but with FSD tech/modern medicine/fresh supplies, they can go and drift however long they want and then come back, or head into the void out of the galaxy.
