Hi, About this very specific ABI issue, one long term solution would be to exclude the PyThreadState structure from the C API, to not rely on it the ABI level.
I started to add getter functions in Python 3.9: PyThreadState_GetInterpreter(), PyThreadState_GetFrame() and PyThreadState_GetID(). I'm working on updating C extensions to use these getter functions, rather than accessing directly PyThreadState members. I wrote a new pythoncapi_compat.h header file (in an exteral project, pythoncapi_compat) to provide getter functions to Python 2.7-3.8. Cython gives me most of the work, since it gets and sets many PyThreadState members.
