-PEP Deferral
-============
+PEP Withdrawal
+==============
+
+The authors have withdrawn this PEP as the core ideas have been implemented over
+time. The relevant features include the :data:`sys.stdlib_module_names`
+API for listing standard library modules, the
+:external+py3.15:option:`--with-missing-stdlib-config`
+configure option for distributors to provide custom error messages,
+and improved :exc:`ModuleNotFoundError` error messages for missing
+:term:`standard library` modules, for example:
 
-The PEP authors aren't actively working on this PEP, so if improving these
-error messages is an idea that you're interested in pursuing, please get in
-touch! (e.g. by posting to the python-dev mailing list).
+.. code-block:: pycon
 
-The key piece of open work is determining how to get the autoconf and Visual
-Studio build processes to populate the sysconfig metadata file with the lists
-of expected and optional standard library modules.
