Like the CoC was a red flag for others. Given, I doubt that anything significant will change with or without its adoption. It was political though and therefore leaves a bad taste.

It is something, but it is clearly not about inclusion or anything. Not that harassment was ever a significant problem in any repository or mailing list I visited.

I think a general request for being polite is always a good thing. Mandatory behavior expectations are not. And this CoC reeks like it.
