[~zolyfarkas], interested in picking this up again?

If Zoltan isn't, would you be willing to work on a patch with Jakob's 
suggestion [~wtff]?

> Currently serializing a nullable field of type union like:
> "type" : ["null","some type"]
> when serialized as JSON results in:  
> "field":{"some type":"value"}
> when it could be:
> "field":"value"
> Also fields that equal the the default value can be omitted from the 
> serialized data. This is possible because the reader will have the writer's 
> schema and can infer the field values. This reduces the size of the json 
> messages.
