The biggest question is simply, who is going to keep track of it? I would like to see a possible idea of letting someone fly 2 classes in a higher class, and then move back. You only get to test the waters once, but at least let them try it and figure out that maybe they made a mistake. Too often people jump in and move up and and realize they are over their head and can't go back. If you let someone test the waters, and then go back, you would eliminate a lot of this.
