The same on a Mac would be frustrating because keyboard navigation, especially for menus, is cumbersome. On Windows (and mostly in Linux too), I can navigate the entire system, application menus and UI controls without touching the mouse or trackpad, relying only on the keyboard. In my experience of using macOS/OS X/Mac OS X as well as Windows and Linux, macOS is one OS where a user cannot avoid using the mouse or trackpad! I agree with your other points (including easier customizability), but have to completely disagree with this quoted sentence.
It's shocking to me how far ahead MacOS is in terms of keyboard shortcuts compared to all other operating systems.
