No, it is orthogonal to Argument Clinic. Usually converting to Argument Clinic didn't change semantic. However these changes conflicted with proposed patch.
Rebased patch is splitted on two patches.
bool_cleanup.patch. It almost doesn't change the behavior. It uses the "p" format unit instead of manually called PyObject_IsTrue(), passes boolean value instead 0/1 integers to functions that needs boolean, and made some arguments ("flush" in print(), "strict", "sort_keys" and "skipkeys" in json module) to be converted to boolean only once.
accept_bool.patch. It makes a number of functions to accept arbitrary objects in boolean context, not just False/True and ints representable as C int. But I prefer first to commit the patch for issue24037.
