It's easy to say "oh, this is just enterprise controls, and your family is an enterprise."

But then I remember every time I've had to delve into actual enterprise administration, and yeah that's its own full-time job.

Side rant: when will businesses acknowledge that an account might be owned by two people (spouses, for example) and allow separate logins for the same account? Their terms of service almost always prohibit sharing passwords, and because the lost password flow would require sharing an email address, you didn't want to do that anyway.
