nip-05 can be used to verify employees too, just add their pubkeys to a nostr.json on the business domain. cash.app seems to do this, surprised more dont.

I think it's a shame one can only have one NIP-05 identity.
The same person can, reasonably, be represented or represent more than one organization (for example, one could be employed in a company and be a member of a non-profit, the two being equally important for that person and fully independent from each other).
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.
