I tend to come down on the side of leaving the wilderness alone as much as possible, but I have to admit I have mixed feelings about that area. It sticks out in my mind as one of the most deceptive bits of trail I have encountered, and the whole Whitney trail tradition is pretty far from being a wilderness situation to begin with, not the same as doing something to the E-ledges on the mountaineers route or whatever (although it is my understanding that some effort was made to keep people from taking a low route on the ledges that people were falling off of).
