This is likely to start more flames than stop future ones, but I have an inkling that enforced, codes of conduct could encourage less participation and diversity as the enforcers have their own prejudices. (For example against developers with limited english language commnuication skills). It could also, and I've seen it happen before, been used to exclude users who can be subjectively labeled by the leaders as 'toxic' when they only challenged the leaders. However, the vast majority of times Codes of Conduct are there to keep people happy and only in the largest projects or rarest times are enforced. This no code of conduct effort would likely cause more strife than stop them, and I wouldn't be surprised if this thread is flagged.
