Comment (by teor):

 Replying to [comment:20 dgoulet]:
 > What if we append the ed25519 base64 pubkey to the `fingerprint` file. I
 worry that there will be confusion on "what line should I send you?" when
 someone is asking for a fingerprint. But, also any line should be fine to
 find the relay, maybe that doesn't matter. And I forsee rare occasion
 someone will ask "Oh give me the RSA fingerprint"...

 That will break any tools that read the fingerprint file.
