what would this be useful for? Either you send the hostname or you don't.

I think what you are looking for is an option to set the Client ID. And when that is set, then that is used. If it not set and SendHostname=true, the hostname is used as Client ID. If SendHostname=false and Client ID is not send, then none of them are send.
