I've had this setup for years now, and never accidentally done this.
Don't forget on a Mac you're much less often moving your mouse to the top right corner (window closing is on the top left of a window.
The further most icons are always the Apple on the left, and Spotlight on the right. Both of which I rarely open by hand. If I'm using Spotlight it's always by keyboard command Cmd-Space (though often I use Alfred instead).
And at least on a Laptop I rarely need to shutdown the Mac, which is all I'd use the Apple menu for. Though again, anything I'd go to that menu for I use Alfred for instead.
May be worth turning it on and see how you get on with it?
