Should JavaJaxRS template family support useGenericResponse parameter?

[msevcenko]

When using swagger-codegen-generators-1.0.50, I was trying to configure the generator to generate the service interfaces in such a way that they use real type as return value, not generic Resposnse. This is setup that I used with swagger 2 which I am now trying to modernize to openapi 3. So I don't want this:

public interface PetApiService {
    public Response addPet(Pet body,SecurityContext securityContext);
    ...

but someting like this:

public interface PetApiService {
    public Pet addPet(Pet body,SecurityContext securityContext);
   ...

which is much preferred - more type safe, easier to implement. The wrapping is then done in the PetApi wrapper.

It seems to me that the useGenericResponse was supposed to control this behavior, that is, by default the return values of services should not be generic, unless you set this option. There is even a template JavaJaxRS/cxf/apiServiceImpl.mustache:

        {{#useGenericResponse}}return Response.ok().entity("magic!").build();{{/useGenericResponse}}{{^useGenericResponse}}{{^vendorExtensions.x-java-is-response-void}}return null;{{/vendorExtensions.x-java-is-response-void}}{{/useGenericResponse}}
    }

which seems to honor this option, but other templates just hardcode using Response and direct delegation between the wrapper and the service.

Am I missing something, or is this something to be improved?
