I think the point was that

derive (.., Binary)

isn't a good idea when communicating with the Non-Haskell part of the 
world. If you write serialisation functions adhering to a specified 
protocol, defining a Binary instance for your types with those functions 
isn't going to do harm.
Only it might give rise to confusion if somebody wants to transmit those 
types according to another protocol.
