Several different places in PEP 1 refer to the python-dev (and python-ideas) mailing list as the only canonical place to discuss PEPs, and requires SC approval for other discussion locations. Nowadays, the PEPs section of the Python Discourse is equally accepted and well used in practice by a number of PEPs, so it should be linked and mentioned therein as well. Likewise, distutils-sig is mentioned as the nominal location for packaging PEP discussion, when the Packaging section of the Python Discourse has been the de-facto location for several years now while distutils-sig sees little to no remaining traffic, and recently was formally switched over on the PyPA specs.

Therefore, I propose updating the PEP to link the Discourse section alongside the mailing list in the PEP, as well as linking directly to the mailing list's web portal for users to subscribe and view past discussions, and replacing references to distutils-sig with the Packaging section on the Python Discourse.

EDIT: Sorry, accidentally hit submit before I was done creating the issue.
