Linus from LTT had a good idea where this comes from, the Apple Silicon in this generation of iPhone doesnt have a better usb controler. That could explain it, the time from defining a cpu to the first device are 4-5 years.

Surely with all the space they saved by removing the headphone port, they could get a controller in there
