Luckily, considering they brought the menubar to iOS (you can open it on most apps if you have an external keyboard connected and hold CMD), I'd say that Apple is at least somewhat committed to it!
Can you imagine if they changed it so that you had to get those actions by doing a 5 finger swipe while hovering over an app (on the trackpad) or clicking 3 times while moving diagonally across?
Ugh I hate gestures. Such a stupid stupid non-intuitive stupid practice.
