The thing is I want it for all my serializers (20+ of them) I don't want to set this in every serializer so since the global config wasn't an option I have to monkey patch AMS in my project to make it behave like I want. I feel like that isn't an ideal situation. Every other library out there that handles API communication can convert casing between whatever is required where. I would have really loved this to be a first class per application setting as well.
