Argument handling is certainly a tricky one - getting positional only arguments requires a bit of a hack in pure Python code (accepting *args and unpacking the arguments manually), but it comes reasonably naturally when parsing arguments directly using the C API.
Perhaps the argument handling for C functions ought to be enhanced to work like python's argument handling, instead of trying to hack it the other way around?
FWIW, Cython implemented functions have full Python 3 semantics for argument unpacking but the generated code is usually faster (and sometimes much faster) than the commonly used C-API function calls because it is tightly adapted to the typed function signature. Stefan
