You shouldn't need a giant, complex CoC to tell people engaging in sexual harassment and creepy behavior to leave. Which is usually the type of stuff people point to for why it's so important to spend thousands of hours debating the rules.

If I've learned anything for Reddit mod culture it's that when you see super involved rules on the sidebar it's still ultimately just post-defacto justifications for whatever emotional mood the mods are in that day. The longer the rules = a good measure how aggressively the mods gatekeeps their community for things that go well beyond the scope of what the community was originally about.

This is how things like Programming becoming lower priorities in such communities than personalities/views of the people running it.

more like "and now we have a CoC, so when anyone is even slightly grievanced, multiple careers will get torched (and not even always the party you'd expect)"

Instead of a tool to be used to solve problems local to an organization or an event, it's wielded as a bludgeon in always the most public way possible (either by the org/conference or target of the CoC itself) and time and again this has shown to be bad for everyone and an endless source of drama.
