    seems like a nitpick, but why are we using both operation and operations in names here?

>
> In the Protobuf serialization implementation, there are some refactorings we want to
make:
> * OperationHandlers take OperationRequest and OperationResponse message, not the parent
Request/Response Object
> * A generic flow needs to be implemented that all OperationHandlers follow. No bespoke
flows for any OperationHandlers... way too much maintenance
> * Use Functional semantics to configure the functionality to extract OperationRequest
from Request (per OperationHandler)
> * Use Functional semantics to configure the functionality to populate OperationResponse
in the relevant Response
> * Have generic Error Handling framework to populate "known" errors and error codes
