--------------------------+------------------------------------------------
 Proposal 220 specifies how ed25519 id keys should be encoded in the
 consensus, but the change has not been implemented yet.

 This is a problem in the next gen HS design, since prop224 specifies that
 the HSDir hash ring should be formed using the relay ed25519 keys, but
 these are not in the consensus which means that the service and the
 clients need to fetch all the microdescriptors before getting an accurate
 picture of the hash ring. Uploading or fetching HS descriptors without
 having all the relay microdescriptors can lead to hash ring desynch and
 reachability failures.
