The streaming services will present a dialog asking if someone is still watching after a period of time. If I do not respond to that dialog, my ATV will eventually turn off which turns off my TV.
That sounds like a variation of a sleep timer. I'm talking about measuring (and maybe even alerting/stopping) excessive watch time. i.e. if someone is actively flipping channels for 5 hours a day, that's not healthy (according to this research)...
Streaming services sadly have the reverse incentive in this case, to actually make you watch more.
