Forcing developers to choose between the speed of the INCREF/DECREF macros and the proposed ABI compatibility mode for the benefit of an as yet hypothetical GIL-less CPython API implementation seems more like a way to kill adoption of the ABI compatibility mode rather than a way to encourage the use of the IncRef/Decref functions.

Indeed, and if the promise of "no-ABI-breakages-till-4.0" is removed,
this would be a non-issue. Keep Py_INCREF macros in the current ABI,
and then break the ABI when someone wants to remove the GIL someday.
That's certainly going to be a big enough change to justify changing
the ABI.
