First, I think this document is extremely well thought out and written, and I think it will be a significant improvement.

I agree with one of the other reviewers that it is not clear that the moderation team is newly introduced in this document. Stating that clearly would be helpful.

I am ever so slightly concerned that the "Security Considerations" section lists potential abuse by moderators, chairs, and "potentially others" and focuses exclusively on "censorship", which completely ignoring the potential for abuse of process by participants. Malicious compliance is somewhat of an art form in the security industry, and the text should make it clear that pretending to comply with the rules around disruptive behavior, while actually trying to subvert them, is itself disruptive behavior.
