Yeah; without commenting on any specific CoC, I'm broadly quite in favor of officially discouraging using official project channels to discuss or say anything that's not explicitly about the project. It's not just a question of making people uncomfortable, it's just... irrelevant. You think there's an issue with a proposed refactoring? Great, let's hear it. You like someone else's new haircut? That's nice, but it is at best spam in project-specific channels.
