Everyone who uses Rick Welch's method of shooting, which includes nose against the back of the cock feather as an anchor, places the feathers about as far forward as shown in your illustration. Mine, for example, are 1 7/8" from the valley of the nock to the back of the feather.
I suppose you could argue that placing the feathers forward has an adverse effect on the ability of the fletches to control the arrow, and if you moved them far enough forward, that would no doubt be the case. But an inch or so further forward than normal doesn't seem to have any practical effect on arrow flight, and those of us who have adopted the nose anchor and other components of Rick's method certainly appreciate the increased accuracy that results.
