We are discussing the requirements for UFER grounds. If a UFER ground is installed then does the NEC still require a supplemental (ground rods) to be installed. In other methods of grounding there is always a supplemental ground.
 
I agree with Dave, metallic water pipe electrodes are supplemented because they may at some point be replaced with a non-metallic water line.

And ground rods require supplementation because everyone knows they're stupid

Sometimes thats all you have though, in the country, well lines are almost always pvc, ufer grounds are much better, but are just catching on in rural areas. I installed a ufer ground when I built my house in 92', way before it was done in residential. Commercial and industrial have been doing it close to forever! LOL! They still do ground rods on cell towers, but they are much deeper.

I've worked on cell sites, they do more than just ground rods. I've never seen so much copper and cadwelds anywhere.

I have, too. Tinned solid #2 copper, ring around everything, rods every ten feet, weld to every corner of equipment platform, weld to both posts of power pedestal, weld to any existing grounding, bond power ground to ring, etc.
