-============
+PEP Rejection
+=============
 
-Further exploration of the concepts covered in this PEP has been deferred
-for lack of a current champion interested in promoting the goals of the PEP
-and collecting and incorporating feedback, and with sufficient available
-time to do so effectively.
+This PEP was formally rejected on 2021-04-14.  The packaging ecosystem
+has changed significantly in the intervening years since this PEP was
+first written, and APIs such as ``importlib.metadata.versions()`` [11]_
+provide for a much better experience.
