pytask-parallel does not call the pytask_execute_task_protocol hook specification/entry-point because pytask_execute_task_setup and pytask_execute_task need to be separated from pytask_execute_task_teardown. Thus, plugins that change this hook specification may not interact well with the parallelization.
