Josh, lack of ability to do something has no bearing on whether or not it is legal. A number of teams lack the ability to waterjet their frames. Is that process illegal? No. How about lacking the ability to code like Wildstang or Kevin Watson? If having those programmers were illegal, a couple of teams at least would be out of the competition entirely!

And the GDC has ruled it legal. Therefore, it is legal, unless and until they issue a ruling that says it is no longer legal.
