I had to cut off the stop only because I perversely insisted on using an 8 or 9 speed-era road front der with a much later and 2-piece mountain bike triple.
Without the stop, the derailleur will kick the chain over the bash guard and off the crank entirely; the reason is that the derailleur has to be positioned high enough (*just* high enough) for the outer cage to clear the bash guard, otherwise it won't move outward enough to shift the chain onto the "middle" ring. Note that my bash guard is the equivalent of a 44 t ring, IIRC; ie, not much bigger that the 42 now in "middle" position. The matching curves is purely fortuitous.
