Being the same is not needed. Ideally the Designer generated war can be customized as needed prior to deployment. But yes consitent behavior and handling of extension metadata should be a goal.

We have arquillian integration tests for the auto generated scenario that may be good to look at as well. Any issues you hit though would be good to bring up.
