Yes, I meant a self-hosted gitea or something. Git itself uses something-with-an-@ to identify people, but doesn't check authenticity, so NIP-05 seems like a good bug-fix, until we get full Nostr logins on gitservers.

We eventually need a note-writer to overwrite commands like git send-email, and we need a way to figure out who to send the note to, and NIP-05 could help with that and keep everything more human-readable. Could always offer npub as a fallback.
