Comment 2 Petr Menšík 2020-10-02 08:41:52 UTC 
Unlike RHEL6, RHEL7 supports algorithms ECDSAP256SHA256 and ECDSAP384SHA384 just fine. But it does not support more recent algorithms ED25519 and ED448, which may lead into the same situation as RHEL6. To my knowledge, no top level domain uses such new algorithms, but that may change later.
