Per T1083 feedback, we could need a Code of Conduct special interest group (CoC SIG):

Decisions by consensus model is weak to get some complicated decisions like exclude a member. @dereckson recognizes it's a worthwhile concern and stresses on the code of conduct for that, with a delegation to a SIG to enforce it with the right to exclude the member.

To draft a CoC is considered important nowadays in open source and free culture, so we need a SIG to write one.
