I don't object to the patch (except it would need to be rebased on top
of the openssl 1.1 patch), but I would like to know a bit more.

What is ed25519? Can a client that supports only that connect to most
or all servers? Can a server that supports only that accept
connections from most or all clients? Are any features lost?
