+Non-goals
+=========
+
+This PEP does not eliminate any existing features from PyPI. In particular, it
+does not replace existing support for GPG signatures. Developers can continue
+to upload detached GPG signatures along with distributions. In the future,
+PEP 480 may allow developers to directly sign TUF metadata using their GPG keys.
