PyLong_Check is two memory reads, bits operation, and comparison with 0. And one non-inlined function call when limited API is used. PyLong_CheckExact is only one memory read and comparison.

I am not sure that the difference is significant enough to justify the optimization. I would require evidences that this optimization is significant if it would be proposed now. But the code is already written in such form, and I am not sure that it is worth to spend our time to change it.
