automatic recreation of service applications after deletion

Service applications will never be created automatically. What you are referring to are the service instances, which - in the MinRole concept - can be made to start automatically on specific servers where in the past you had to start them by yourselves on the servers you wanted. If you delete a service application, you will always need to recreate it manually.

Service applications are logical containers which primarily hold configuration and security information. For most service applications you still need some physical components to be activated in order to do the actual work - those are the service instances. They can be started on one or more servers, and in the case of MinRole, can be started automatically for you if they are stopped.
