Those features include Dashboard regions and Safari RSS line clamping).  Eventually we just decided to merge both into a common prefix, but we wanted to keep the old property names working for compatibility.   It was convenient to just map both to -webkit- rather than actually checking the specific property names and only supporting either -khtml- or -apple-.
