Feature or enhancement
Starting in Python 3.12, it is possible to receive vector calls in the limited API. However, it is not possible to issue them from a binary extension module compiled for the limited API.
Pitch
Since the PEP-590 is presumably stable at this point, I propose exposing more of it through the limited API. This would entail the functions
PyObject_VectorcallPyObject_VectorcallMethodPyObject_VectorcallDictPY_VECTORCALL_ARGUMENTS_OFFSET (a macro constant that is needed to use these effectively)
