"maybe the test suite should error out if any unexpected symbols appear in the stable ABI?"

This or on build (personally I prefer this sort of validation at build time, but I know others would prefer to defer it).

We have a script now that can extract all the right functions, though I think it'll only work in the source tree as it relies on clinic. But that should make it fairly straightforward to spit out a list and compare it to a checked in list.

At the same time, we have a problem in the current release, which is the functions I listed earlier. I would really like to fix that without blocking on getting the right long-term fix (since the immediate fix only affects one file in the Windows distribution, though it has implications for supportability).

It probably shouldn't, but it needs an #ifndef Py_LIMITED_API check so it is excluded from the headers (my list was automatically generated).

It sounds like the opt-out approach isn't working very well, and maybe an opt-in approach should be considered instead? I recognize that the way C headers work makes this difficult, but it seems like something needs to change. 

Or maybe the test suite should error out if any unexpected symbols appear in the stable ABI?
