Most of the public functions in the C API have named parameters and both of these functions are documented with named parameters:

https://docs.python.org/3.15/c-api/module.html#c.PyModule_FromSlotsAndSpec
https://docs.python.org/3.15/c-api/module.html#c.PyModule_GetToken

While wrapping these APIs for PyO3, I noticed that the public definitions just have types for the first parameter without an explicit name:

cpython/Include/moduleobject.h
