Sorry for the bad timing. I dislike working under pressure. The discussion on python-dev, the bug tracker and pull requests was really interesting.
The issue has been fixed: the whole idea of stable ABI for PyConfig has been abandoned. If you want to switch to a different version of Python when you embed Python, you must recompile your code. It was always like that and the PEP 587 doesn't change anything. PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() initialize PyConfig to sane default configuration. So if we add new fields in Python 3.9, you don't have to manually initialize these fields, except if you explicitly want to use these new fields to benefit of new configuration options.
