arseegee,
No change in the code rule, however in the '96 and earlier codes this rule was Exception #1(a) to 250-94. The rod really isn't a very good electrode and it will never carry very much current into the earth. A #6 is more than enough copper to carry the current that the rod can put into the earth and that is why the rule exists. There is no electrical advantage to installing a larger GEC to the rod.
