Not sure it would work as well in a phone as most of them live in cases. That said Face ID at the moment isn’t great when you are out and about.
Under-screen reader and Face ID is a better solution imo.
That said, fairly sure the iPhone 13 design and specs are pretty much set at this point. When you need to produce millions of these things per week it means the entire supply chain needs to be built out and ready well in advance. These things are often called diseconomies of scale - e.g. the more you need to make of something the more difficult certain things become, like making design changes or quickly changing direction.
After a certain point, having to produce something in such huge quantities just makes thing harder with very little reduction in unit cost.
