No it’s not common for two pieces of code within a single process to communicate by serializing the protobuf into the wire format and deserializing it.
It’s however somewhat common to pass in-memory protobuf objects between code, because the author didn’t want to define a custom struct but preferred to use an existing protobuf definition.
