[openssl-users] is there an API to list all the TLS 1.3 cipher suite names?

TLSv1.3 ciphersuites are enabled even if you explicitly say to disable them.

    $ openssl ciphers SHA384:\!TLS_AES_256_GCM_SHA384
    *TLS_AES_256_GCM_SHA384*:TLS_CHACHA20_POLY1305_SHA256:[...]

    $ openssl ciphers AES:-SHA384
    *TLS_AES_256_GCM_SHA384*:TLS_CHACHA20_POLY1305_SHA256:[...]

That doesn't seem right.  Am I missing something?
