That's what KDE does. But it goes against the principle of parsimony:
having two similarly accessible methods of doing the same thing slows
people down, by making them dither. (For example, it's okay to have a
title bar close button and a "Close" menu item, but having two close
buttons is bad. Similarly, having two scroll-up buttons would be bad.)
