Yes, this is true. However, the transition of `omp.wsloop` to be a wrapper rather than defining the whole loop will be part of a separate patch. So, after this patch alone, it's not expected to use `omp.loop_nest` inside of `omp.wsloop`. These tests just needed to add a "future-wrapper" parent operation so that the new op verifier could be tested.
