if you see the differences of face id hardware between iPhone 12 & 11, then you will see its almost identical. Besides A13 & A14 bionic chip both are very powerful. so Apple is intentionally doing this to compel customers to upgrade their iPhone just like when they added night mode on iPhone 11 but not on iPhone X & XS though they were capable of having night mode.
You are talking about cosmetic differences, we don’t know if there were any changes under the hood. If Apple wanted to intentionally limit this feature, why would they allow it on iPhone 12? They could only allow it on the latest iPhone series. It doesn’t make sens to limit the feature specifically to last year models without an hardware limitation

Really looking forward to this release.

These releases are a reminder that even though fans, media, tech pundits obsess over hardware, it’s software that really moves the dial year-to-year. Even Apple has lost the right balance, which is understandable since they make their money on hardware. But to be great at hardware, you need great software. And to make a ton of money at services, you have to be great at software.

I used to buy tons of music and books from Apple. But iTunes was so buggy for so many years with confusing, half-baked interface, I just moved to Spotify. Same with movies many years later. I used to buy a ton of movies, but the library tab doesn’t work with large libraries, so I rent movies through Verizon or Xbox now.

I hope Apple really gets the balance back. Great software will feed the revenue ecosystem if you let it.

this update is nothing for me as I am currently using iPhone 11. its very sad that how greedy Apple have become.
There is only one feature that is not avaible on iPhone 11, and it’s probably because of hardware limitation or greater security risks on iPhone X/XS/XR/11. The rest of iOS 15.4 is still a good upgrade for everyone
