It is weird that they acted as through the design system hasn't changed much since iOS 7. They've overhauled and tweaked it every year since 2011- increasing font weights, using slower floaty/bubble animations, increasing corner radiuses and adding more negative space, adding depth and shadows to icons, etc. Control Center, for example, looks nothing like it did in iOS 7. iOS 7 was much more minimal, the least skeuomorphic, and a bit more geometric than the "neumorphic" changes they've made since then.

This updated design language seems to have similarities to Microsoft's Material/Fluent design system that brought more of that same glass material to Windows 11, with the more 3d-looking edge outlines on ui elements. So the glass metaphor seems to be a trending metaphor in these UIs, for better or for worse.
