Now it started failing on a different place:

======================================================================
FAIL: test_export_symbols (test.test_capi.CAPITest) (name='PyThread_get_thread_native_id')
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/..../cpython-main/Lib/test/test_capi.py", line 662, in test_export_symbols
    self.assertTrue(hasattr(ctypes.pythonapi, name))
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AssertionError: False is not true

Looking at the test, is the expectation that all OSes must implement it since 3.11?
