+
+If an API introduces a non-discoverable, backward incompatible change, and
+such change is not backported to all versions supported by Tempest, tests for
+that API cannot live in Tempest anymore.
+This is because tests would not be able to know or control which API response
+to expect, and thus would not be able to enforce a specific behavior.

+If a test exists in Tempest that would meet this criteria as consequence of a
+change, the test must be removed according to the procedure discussed into
