I agree, I think this is what they meant. A feature for the people who have an iPhone 8 or 9 who say “why would I upgrade, my current phone is fine”.

If you can use this tech to make a feature that they really want you can trigger upgrades that otherwise may not happen for many more years. We’ve seen that before with things like when Apple first released a bigger phone. That triggered a LOT of “early” upgrades that wouldn’t have otherwise happened.
