The difference between setting some community norms and having a code of conduct seems to be writing it down. And, in writing things down, there's one reference for the rules/guidelines and everyone knows what they are. Is much prefer GitHub to set some rules rather than have year's worth of what would essentially become case law. Plus, community norms aren't exactly working either, so.. Overall, with a bit of editing (perhaps the code of conduct should be rewritten to avoid as many politicised words as possible), I'm not sure where the difference is between a well written code of conduct and a 'be nice' community norm.
