My thinking here is only to end the need to have this conversation, but
having this conversation is probably best, so please ignore this comment.

For example:
 - notif-netconf-client   // uses /ietf-netconf-client:initiate/...
 - notif-netconf-server   // uses /ietf-netconf-server:call-home/...
 - notif-restconf-client  // uses /ietf-restconf-client:initiate/...
 - notif-restconf-server  // uses /ietf-restconf-server:call-home/...
 - notif-coap-client      // uses /ietf-coap-client:initiate/...   (TBD)
 - notif-coap-server      // uses /ietf-coap-server:call-home/...  (TBD)
 - notif-http1.1-client   // ???
 - notif-http2.0-client   // ???
 - notif-syslog-client    // ???       
 - etc.

And, for interoperability, we'd have to pick a mandatory to implement
transport, which would it be?
