That code will work well if KIP-331 is merged. However, the lambda expressions will fail if we add default implementation to all methods of Serializer (ditto for Deserializer). KIP-336 had discussed such changes which may happen in the future. That is why KIP-331 doesn't add FunctionalInterface annotation to Serialize and Deserializer.
