I wonder why that doesn't seem to count, I guess it's because to me the "claw" is part of the derailleur rather than part of the frame - many bikes that use them have cheap derailleurs that have an integral hanger. But I have an old steel frame for which I had to buy a claw when I built it up. Strange.
