What I suspect is happening is that both of you are confusing policy development functions of ICANN with the operational and technical functions of IANA, and applying inappropriate mental models drawn from the former to the latter. In policy development we want “openness, diversity, inclusiveness and the user perspective.”  In the DNS IANA functions the users are the registries, it’s an intermediate good, it’s all about implementation, so we want efficiency, security and direct accountability to the primary users, not some playground for different stakeholders to voice their opinions.
