Review comment:
       If we're talking about scopes, wouldn't it be more intuitive if one of them was `CLIENT`? Since these definitions go into the protocol definition files that are used by other clients, this could be used to differentiate between protocol apis that clients need to support versus protocol apis that are used for inter broker and broker -> controller communication.

Review comment:
       The network package is not meant to access requests, right? Could we make it work by changing the supplier to something more generic?
