Yes, android has had all this working for years, on phones and tablets alike.

It's not trivial but I'm not going to give a trillion dollar company reprieve for a feature standardized in all of its competition.

As the poster before you said, they have already built it. They have already solved those issues. They only offer the solution to schools and big organisations that use their management software to control lots of devices.

Use cases in family context is different from that of schools and businesses, both in terms of account management and in terms of user journeys.

So I’m not sure the infra for those edu and commercial use cases would work elegantly “as is” for a family setup.
