I don't think so. Like any other pro tool it has a learning curve which without a little time investment renders the tool useless. I think the only telling thing about Apple's choice of window management features is that they shoot for the lowest features possible so that users can learn them all as quickly as possible. On-boarding > user control for Apple.
I think the GUI that Apple ships is successful in so far as all of its features are literally visible. You literally have a mouse and a clickable pad, you always have maximize/minimize buttons. Any more advanced software has "hidden" features in that they hide behind menus and hotkeys. Though everything that is hard about "modern" computational interfaces is that discoverability is shit, see [1]
