Traditional vertical dropouts don't allow for any forward/backward adjustment; these allow for a few millimeters adjustment. Why? I don't know.If the frame is build straight, you shouldn't need any such adjustment. But it could be handy for chain tension adjustment if you use the frame as a fixed gear ride. But then you wouldn't need the derailleur hanger. Go figure.
