yes please, we are deprecating hex. you will have to promptly convert back to hex on the nip05 side... 😅... but we are trying to move away from humans using hex keys for everything.

This spec exists because I accidentally pasted my hex privkey in a note thinking it was my hex pubkey 😆

It's not just Damus, it's NIP-19 https://github.com/nostr-protocol/nips/blob/master/19.md This way it's easier to distinguish btw pubkey, seckey or event id than hex representation.
