IMO it's newsworthy that this feature is going to exist and a lot of people outside of the tech world have no idea unless someone tells them about it. We've been reading about "phone addiction" in newspapers for ages, now there are tools to help manage it.

If you're a parent of teenagers with iPhones this is a pretty big story and the headline at least answers the implied "did it work?" question instead of trying to bait you with it.
