Thanks Peter, that's a good clarification.
Simon's email about a possible future HPy backend for Cython also reminded me about a detail of the way pysip and cffi support the stable ABI: the modules built with those tools are abi3 compatible, but the support modules that the tools publish to PyPI are *not* abi3 compatible.
Does it mean that ABI stability of a module built with pysip / cffi then depends on the ABI stability of the "support modules" published by pysip and cffi?
I understand that this allows to decouple of evolution of the stable ABI from Python versioning, is that right?
