   Regarding using Deployment for instead of Pod, I generally agree but I think we need one consideration.
   
   Some interpreters (like markdown, jdbc) are stateless. So Pod can silently be re-created.
   However stateful interpreters, like Spark, Python, when Pod is re-created, it loses all states and users need to know about that.
   
   So, unless we have some mechanism to notify a user about Pod re-creation, I think it is not a bad idea to let Pod disappear and let the user get an error message about that.
   
   What do you think?
