Description

The current code uses a single configuration flag to control both. We should use separate flags in order to allow usage of port multiplexers such as sslh where we need the client to send its identification string (thus triggering the correct multiplexing), but we might want to wait with the KEX-INIT until receiving the server's identification - e.g., for special customization of the KEX phase based on the server.
