Which API should be used in C extensions to be "subinterpreter-safe"? Currently, Py_None is a singleton shared by multiple interpreters. Should suddenly all C extensions use a new Py_GetNone() function which returns the per-interpreter singleton? If yes, that's basically what my PR 18301 does:

   #define Py_None Py_GetNone()
