This code path looks like a micro-optimization (to avoid PyNumber_Index). I don't think that it's worth it.

Not only. Many functions like PyLong_AsUnsignedLong() and PyLong_AsUnsignedLongMask(), many setters and converter, only call __index__() if the argument not int. So there would be a subtle behavior difference when the argument is an instance of the int subclass which defines __index__(). And calling __index__() for int subclass adds overhead.

But this is not completely consistent, so this may not make large difference.
