Without meaning to encure your wrath Manchild, it is technically legal.
Although it is clearly an infringement of the rules, it passed the test and is officially considered safe and legal, also, I must say that Williams would have done the same if such an opertunity had arissen in their hay day, and although it is clearly vandalising records such as the one you mentioned, I think its good that the teams have found it. F1 is about technological advances. Unfortunetly it is not always for good esspecially if a rival team finds it first.
