Hosted API Service - Singleton or similar

Hey there,

I really like the idea of creating my own service.
Code genereation makes it very easy to implement the API inside the client code.

However, I’d highly appreciate if the Singleton (or similar) pattern could be applied to the generated client service.

Of course I could apply this on my own very quick but i would have to do this step every time I update the service.

Let me know what you think of the idea.
