draft-ietf-sshm-ntruprime-ssh-00 asserts that it's identical to the
@openssh.com version we already implement:
'[sntrup761x25519-sha512@openssh.com] became the default key exchange
algorithm in OpenSSH during 2022. That is identical to the
"sntrup761x25519-sha512" mechanism described in this document.'
