If there are people cheating then the correct thing to do is confront these people at the time that they are being acused.
Making rules for unproven situations does nothing but make rules which are unneccesary and only serve to provoke the people who do not cheat. It would be interesting to have the experts who make these claims about judging yardage with binos to demonstrate this method at some of the national shoots to justify their reasoning. The rule is here and will stay, so is the dead horse.
