It should be possible to create a product and add an existing/new backend later on. No need to automatically create a new backend when a product is created.
The idea is that product and backend are two different things that can be independently created and linked together at will. All services are/will be products and there will then be no need for a checkbox.
We create a default backend that comes with the default product. But when you create a new product we don’t create a default backend...which is what this issue is about.
