Those particular steel rings were an unpleasant addition, but these Campagnolo steel rings look quite decent and probably work smoothly and shift very well.
This is the first I have seen of steel Campagnolo chainrings however.
Even the 1970's-era three-arm Gran Sport crankset (or whatever it was called) had steel crank arms but aluminum rings (riveted together to form a single unit that then bolted to the crank arm).
