While I have no issue with the proposed policy, have already agreed to it and am thankful for this issue being tackled, I suspect that some words of transparency on how this proposal came to be might be helpful for users just stumbling into this.
To me (non-native speaker) proposal sounds like something yet to be discussed and which might be subject to changes before being finalised.
The post above states that the proposal needs to be accepted though or people need to leave.
So I guess this has been discussed in a SocialCG meeting? And another reason is that this community is strongly related to the W3C, so their code of conduct is the one we adopt?
