Background on why this was the default before: For the simple "rect" SHP finder (which is no SHP finding- just averaging in a rectangular window like basic multilooking), the results can sometimes look much better if you mask out very bright pixels (which dominate the sum in a window).
Since the normal default uses the GLRT SHP algorithm, that algorithm should take care of this problem on its own; users picking the rect method can choose to turn this back on as well.
