I believe the idea would be to eventually use `omp.canonical_loop` in place of `omp.loop_nest`, while adding loop transformation support in the process. In the case of a `do` construct, for example, we'd still split the worksharing semantics (`omp.wsloop`) from the loop itself (`omp.canonical_loop`), which could potentially be impacted by any number of loop transformations. Clauses related to data sharing would still logically belong to the loop wrapper.
