Actually, the Code of Conduct is intended to be all-encompassing:

  Where does it apply?

  The Code of Conduct applies generally. If you
  participate in or contribute to the Go ecosystem
  in any way, you should
  observe the Code of Conduct.

So, golang is a way of life, according to this CoC.

What I meant by off topic is that any "Romantic or sexual commentary, remarks, or questions" in a Golang communication forum are off topic.

Having that go against the code of conduct does not necessarily suggest a puritan view of the world, but an understanding that those are rarely constructive to the conversation.
