I do not see any reference as to how to use the ed25519 signature algorithm in SSH.  Perhaps I am missing a reference somewhere, but it really seems that the use of the signature algorithm in SSH should be defined somewhere, preferably in an IETF document.  I so not see the point of publishing the SSHFP record document without some reference as to how it will be used.
