Well, that's the obvious alternative to PEP C.
Armin Rigo's PyHandle idea may be a good start? https://pythoncapi.readthedocs.io/pyhandle.html
I think the PyHandle idea has the best chance of producing a good end result. I suspect PEP C doesn't go far enough to solve the problems for alternative Python implementations. They really want PyObject to be an opaque handle-like object. Trying to make the existing C-API work like that seems like a nearly impossible task.
Why do you think so? It looks like a relatively simple change to me, mostly just replacing "Py_INCREF(obj)" with "obj = Py_INCREF(obj)" in user code, and then clean up a couple of corner cases here and there.
It would obviously break the world, but that's the whole point, right?
