Just because you don't think it's a big deal, doesn't mean it's not. Especially when you haven't got anything except your opinion to back up your argument.
Why do you think so many are clamouring for TouchID to be reintroduced on phones? Why do you think Apple introduced unlock with Apple Watch? All those comments on threads annoyed with Apple for forcing them to buy a watch to unlock their phone with a mask on.
Of course people would love a better system that doesn't have them entering their passcode 50 times a day. To suggest otherwise is perplexing. Just search Google. Besides, the world isn't just the west, ya know. A few people in Asia might be pretty keen on such a feature.
Absolutely Apple would just release this for their new phone. Hey, I could be wrong, but there is precedent for Apple doing this. But this is just fantasy at the moment. I will say it again, I doubt the legitimacy of the rumor.
