 Review comment:
   At least some of the Proton 'client' bindings, perhaps AMQP.net lite (though 
its lower level and probably expected for you to configure it), probably 
Dispatch...and I'm sure there will be others. I'd say I'm currently more aware 
of things not setting these bits, or likely not to be, than I am those that 
actually are.
