        For v3 the interface or abstract class handler methods declare a method parameter for the body parameter--if one is
        specified in the OpenAPI operation declaration--in addition to the request and response. The routing code extracts the
        body parameter from the request content and passes it to the handler method.

        For v4 the generated handler methods do not declare the body parameter as a method parameter. Instead body parameters are
        dealt with, as all other request parameters, by the user-provided code (when an interface is generated) or by the
        generated code (when an abstract class is generated).
