Let me provide you with a menu to select from:
1) What's that JSONResponseBuilder from #7136
2) Where should docs about API development go (especially about how to do errors, streamline responses, ...)
3) How do you feel about refactoring the complete API code to streamline responses?
4) Where should code live for handling any errors during API usage and handling responses for success stories? Should this still be WrappedResponse + AbstractApiBean methods or should we go somewhere else?
