Also cannot change the taskbar icon size anymore either. I always enjoyed small icons + full taskbar button size as it allows one to have a larger target to click and see the window name all at once.
Agreed about the macOS dock. I occasionally use macOS as well and it kind of reminds me of a terminal bell in tmux, it just lights up for anything and everything. Windows at least has different colors, solid vs blinking, and even progress bars through the taskbar icon.
