I don't understand the
(void*) &(PyABIInfo)part. Where is this variable declared? Or does it magically accept the PyABIInfo type here?I would prefer keeping
_Py_INTERNAL_ABI_SLOTname to discourage developers to use it in their project.If it's technically possible to use a macro in a C extension, someone will do it and then it will be hard for us to change the macro (users always complain).

It's a C99 compound literal. Yes, the value “magically” appears here.
This feature safe to use but not part of C++ and therefore not suitable for our public API.
I think the underscore is enough of a warning here.
(If it wasn't for the the C++ incompatibility, I'd have made this public and replace the currently recommended two-liner. Also, due to the stable ABI, we can't change much about the macro anyway.)

I would prefer to keep the
#ifdef Py_BUILD_COREguard, see my comment below.
