I think as ground ring is probably the most effective electrode if sparky gets there after the footers are poured but the price of the copper makes it cost prohibitive. The state put it in the bid for the toll booths and radio towers in addition to Ufers and rods. They wanted good grounds. The Ufer connection being made available is part of the 1&2 family structural inspection here so it ends up being pretty universal.
