Tim, let me step in as a new sponsor for Python SIG FAS group.
First of all, let me try to explain what this FAS group is and what it isn't:
The python-sig FAS group is a group of Fedora packagers with permission to commit to all packages where the group was added s a co-maintainer. Today, that's 38 packages [1], not big number, but still big responsibility. Also, this number will increase in the future, hopefully. Only trusted packagers can be part of that group. Hence the 5 packages criteria mentioned on the wiki, so non-packagers or people with one package won't apply.
The python-sig FAS group is not a group of Fedorians who like Python. For that purpose, one can be part of the informal SIG, i.e. join the mailing list (python-devel), hang out on IRC (#fedora-python), add their name to the wiki page. Everybody is welcome to do that. If such person happens to be or become a packager and becomes known and trusted, (s)he might end up in the FAS group as well, later.
The python-sig mailing list is not a secret place we don't want anybody to let in. It's a technical way to distribute e-mail from Fedora systems to all members of python-sig FAS group. Such e-mail include e-mail from bugzilla. As those might contian sensite information, the mailing list is private.
If you want to be on the list just because of the list itself, it is not going to happen (for anybody). If you want to join the FAS group, talk to me or other sponsors and make me/them believe you are the right person for the job. I don't know you, so I won't sponsor you. This might change when I become to know you trough you extensive work on Python packages in Fedora and/or EPEL.
You mentioned that you need to be on the list because your work depends on access to security information. Since your activity in Fedora is maintaining a single package, none of the current sponsors feel confident to trust you with that information.
But if you want to talk (perhaps privately) more about what you need and why, maybe we can come up with a better way than the FAS group to share security updates with you (or Intel).
