Comment (by cypherpunks):

 By default server follows client's preference. It depends
 [https://www.openssl.org/docs/ssl/SSL_CTX_set_options.html#item_SSL_OP_CIPHER_SERVER_PREFERENCE
 SSL_OP_CIPHER_SERVER_PREFERENCE] option.
 Is it worth to prevent any possible client's insecure choice or to allow
 client to chose it's own destiny? (if something wrong with one of cipher
 then client's software would be updated faster)

 Either way, server's cipher list should be ordered for clarity, just in
 case and for future.
