+.. warning:: No new modules are to be added to this PEP.  It has been
+             deemed dangerous to codify external maintenance of any
+             code checked into Python's code repository.  Code
+             contributers should expect Python's development
+             methodology to be used for any and all code checked into
+             Python's code repository.
