What about the situation where a package is not compatible with newer
versions of python so does not need a PYTHON_COMPAT change?

I don't think you can assume PYTHON_COMPAT is outdated for a package
just because it doesn't have the latest versions of python
listed. The only time you can know for sure that it is outdated is if it
lists a version of python that no longer exists in the tree.
