Maybe Rob Pike can say something about this CoC thing. Don't really like the way Russ does things.
For me, CoC is where programming meets politics. Whom gained benefit from their current position is likely to impose those rules to protect their now interest.
Pretty much there is a soul behind each language, Ricky Hicky for Clojure, Guido van Rossum for Python, Matz for Ruby, and Rob Pike for Go. Those people are not insecure, and I never felt them to be so aggressive.
