ssl_reject_handshake disallow TLSv1.3

[rjvbzeoibvpzie]

ssl_protocols  TLSv1.2 TLSv1.3;

server {
    listen 443 ssl default_server;
    ssl_reject_handshake on;
}

This does not allow ANY other server to be reached with TLSv1.3

server {
    listen 443 ssl default_server;
    ssl_certificate ssl/cert.pem;
    return 444;
}

This allow ANY server to be reached with TLSv1.2 or TLSV1.3 (as
configured).
