_PyImport_GetModuleId()

Isn't this for _Py_IDENTIFIER()? What's using it?

_PyInterpreterState_IDDecref()
_PyInterpreterState_IDIncref()
_PyInterpreterState_IDInitref()
_PyInterpreterState_LookUpID()

Aren't these used by _xxsubinterpreters?

_PyImport_GetModuleId()
Isn't this for _Py_IDENTIFIER()? What's using it?

It seems like nobody uses _PyImport_GetModuleId(). Maybe it can just be removed.

A code search on _PyImport_GetModuleId regex on PyPI top 5,000 projects found no user of this function.

_PyInterpreterState_IDDecref()
_PyInterpreterState_IDIncref()
_PyInterpreterState_IDInitref()
_PyInterpreterState_LookUpID()

Aren't these used by _xxsubinterpreters?

These functions are only used by Objects/interpreteridobject.c and Python/pystate.c. These functions are not used by shared extensions, so there is no need to export them.

What I can say is that tests pass on all platforms :-) So _xxsubinterpreters looks fine.
