There are some details like padding (to maintain quad alignment), but
this completely decouples the encoding politics from the transport layer.

Remember the content-id field I asked about awhile back?
This can be used for that.

Rob touched on the $64 question in the meeting that got ignored

How do you know which protobuff it is? Is it gNMI? OC-telemetry? vendor
gRPC data?

Perhaps:

  encoding-id = gpb/gnmi
                      = gpb/openconfig-telemetry
                      = gpb/example-bgp-state
