Google Play Games still doesn't work with Family Link

Google Family Link, a way for parents to create supervised/limited accounts for their children, has been slowly rolling out to more regions over the past year. It's largely feature-complete at this point, but there's still one pressing issue - it doesn't work with Google Play Games at all. Child accounts are unable to log into Play Games, which prevents many titles from saving progress - and some from working at all.
