To me, the http:yes option implies adding http support on top of the normal
amqp. Setting role:http would make it clearer in this respect. Since nobody
else complained, I am not sure if implementing the change is worth the
effort, though. Maybe just document it?

Instead of

                    "description": "Accept HTTP connections that can
upgrade to AMQP over WebSocket",

write

                    "description": "Accept HTTP connections that can
upgrade to AMQP over WebSocket. Plain AMQP connections are not accepted on
this listener.",

?
