Frankly, the icon grid was arranged somewhat arbitrarily to begin with. I'd be quite happy to have a largely-alphabetical list, making it much easier to actually find the specific preference pane I'm looking for.

Instead of distinct readable controls with clear interactions it's a sea of gray upon gray upon gray.
It breaks Apple's own HIGs which says not to (over)use switches, and use checkboxes instead. The drop downs no longer look like they can be interacted with.
Where you'd have settings that can easily fit on a single pane in multicolumn view, you now have lists upon lists upon lists that are entirely alien to the Mac OS https://twitter.com/oskargroth/status/1534133558817742848
Interface consistency is a bullshit goal: https://twitter.com/MarioGuzman/status/1534585939971801088
