          Proposal updated to reflect clarity added under section 3.1.4.
          The proposal previously read as follows:

          The server MAY disconnect the client if the protocol name is incorrect. If the protocol name is correct, but the version number is
          incorrect, then the server MUST flow a connack rc=0 and then disconnect the client.

          This is already in the spec from WD08 (MQTT-6). See section 3.1.4 response and 3.1.2.2 protocol level (WD10).

          Previously: see MQTT-6
