Thanks Karsten. Now that I know this isn't a completely foolish
question adding tor-dev@ back in.
If we're dropping the fingerprint that's a lot more invasive.
Fingerprints are relay's canonical identity, and simply dropping them
will break... a lot. I'd suggest instead relays should continue to
have a fingerprint but that it's the 40 character hex hash of the
ed25519 identity.
On a side note it would be nice to have a spec patch before changing
things this time. Sections 8 and 9 are a fine summary, but it's not
clear to me precisely how the descriptors are changing from it. They
certainly don't say to me "we're dropping the fingerprint field". If
that change went out without a spec patch first I'd borrow Mr. Potato
Head's angry eyes to stare at its author.
Cheers! -Damian
