Unfortunately, the primary belief is that nip-05 is to be used as just a human-readable identifier. It's always been my belief that nip-05 was used verify you based on the fact it's either a domain you own, are the primary controller of, or directly represent in a offical capaicty a person of the other two catagories. It's why I don't have a nip-05 address myself. I don't have access to a domain that fits those catagories.
