FYI, you can be added to the family share and control if and which paid content/subscriptions you share.
You can disable purchase sharing and specific subscription sharing on your apple device. You will still be able to view any shared subscriptions (i.e., appleTV and MLS). This should alleviate the headache of multiple accounts and login repetitiveness
mgarbowski pointed out earlier in the thread.
That being said, as I am not an apple user (and don't have content or subs other than appleTV + mls), nor do i know any. I haven't been able to test this but based on the screenshots below, it should be pretty simple.
Screenshots are from the apple support site.
