"""You can do your own thing in "Contrib/<GitHubUserName>/...". Everything that appears there coming from that user I will accept blindly (well, if it is legal). It is your own playground. You can still advertise what is in there in the root README.md. Everything changed outside Contrib/ needs to be discussed/reviewed more properly. Everything changed inside Contrib/username by other usernames needs the same review treatment."""
