Nightshift is nice, but I don&#x27;t understand why CarPlay, Edu, Health are not just app updates. I don&#x27;t see how they warrant a whole OS update when really it&#x27;s just a few extra features added to existing apps (none of which I use or plan to use, unfortunately).<p>I guess it&#x27;s just convention by this point. Feature updates across the board periodically, then security updates in between
