+Subject: [PATCH] Force using importlib_resources in Python < 3.9
+
+Force using the external importlib_resources package based on Python
+version rather than the presence of the built-in importlib.resources.
+The latter does not have the needed files() method in Python < 3.9,
+and therefore results in test failures:
+
+  E       AttributeError: module 'importlib.resources' has no attribute 'files'
+
+This affects specifically Python 3.7 and 3.8 that have an older version
+of importlib.resources module.
