It's hard to answer in general, but does it have to be answered in general? I could imagine supporting a policy that infinite scroll in particular is addictive and app developers can't use it without strong warning labels and time alerts.

Maybe not? Maybe if enough minors experience harm from a platform, that's enough to restrict it for minors.

100% yes. Remember, this is somewhat adversarial: Meta increases its products addictiveness year by year. Banning individual practices fails if the rate of that growth exceeds the impact of point solutions.
