The main use case here is "flinging" with a trackpad.  In that case, Emacs already responds by scrolling up/down to the top/bottom.  It is after Emacs has hit top/bottom that the "extra" beeps occur.

If already at the top/bottom, the normal thing for OSX apps is to "bounce" a bit to show that the display is already at the top/bottom.  If at the top, the whole page is moved a bit downwards and then bounces back.  This is not common in X, so not really appropriate for Emacs.
