Got it, thanks for the clarifications! Tracking 3.x Python versions is fine. We already need to do that to support things like new bytecodes, and PyTorch supports an explicit list of 3.x Python versions with separate builds for each.
Tracking 3.x.y Python versions would be much more painful, and make us need to rethink our approach. So what Steve Downer described as "remain compatible within a single 3.x release", seems like exactly what we want. I support that level of compatibility guarantee. Could we keep that guarantee with this change?

Well, my plan is not break these internal C API just for fun. It's only to better "advertise" the separation between the "stable" public C API (backward compatibility warranty) and the "unstable" private/internal C API (can change any time, changes are not documented).
