Is this interface that much different from "classic" OSX preferences? The old panel with horizontal icons was replaced with sidebar tree which loads sections withouth need to return to main screen - that is pretty much convenient.
But I do agree - settings panels not only in OSX become too complex and often featuring stuff that should stay on mobile devices. It's been years but I'm still not fond of all sorts of notification centers and destkop applications being able to nag you with their stuff.
On top of the list vs grid, it was reorganized into multiple layers, universally understood controls were replaced with new ones never used on macos before, universally appreciated design elements like containment boxes were removed, native controls were (at least in some places) replaced with web-based look-alikes, recognizable ucons were replaced, decades-old terms were replaced...
