Hi nusenu, that's fair. We've begun to conflate a couple concepts here...

Isn't using "fingerprint" not a bit misleading since it is not the output of
a hash function but the ed25519 master public key itself?

Thanks Sebastian. In that case we should put more thought into this
because fingerprints are foundationa

That is because tor drops trailing '=' from base64 encoded values
within descriptors. Some fields indicate this within the spec, others
don't.

I've put together the text, if you have any
comments please let me know. I'm planning to submit it
soon-ish.

I'll also send it to the tor-relays mailing list.
