Oh come now. There's a difference between a real life situation where there's an actual reason for a certain product to perform a certain task, and a competition where something is arbitrarily decided to clarify the rule. Knowing the way the first guys usually work, i think they would've emphasized that they'd made the rule to emulate real-life situations rather than saying it was to clarify a rule... I may be wrong. W/e, I have no doubt in my mind that that WASN'T their intention in making the rule.
