CEA has been doing 2 stunt sequences WAYYYYY before 2010. I dont know why it came as a shock then. Maybe because they had a "highlighted" stunt, but whichever the case may be, the score sheet evolves and in return pushes the industry in a new positive direction. What is legal now, was not legal a few years back. Obviously we know, these atheltes are capable of difficulty so why limit it.
