Title bar to go in Gnome 3.4?

According to the Fedora Wiki in Gnome 3.4 "maximized windows can gain more screen real estate by hiding their title bar."
The title bar above a maximised window has always seemed like a waste of space to me. The information it contains is redundant as the same information is visible in the panel and the address bar. Why not hide it?

In Gnome 3 the function of the close button in the title bar is duplicated in the panel icon, where the right-click options from the title bar could also surely be duplicated.
