Even with detached airflow, wouldn't there still be a real benefit to filling in the wake? It wouldn't be optimal, but it looks a lot cleaner than simply leaving a large square hanging out back there to hold you back. I'd expect that "slightly detached" airflow would be a whole lot better than "completely abandoned" airflow. I'm thinking along the lines of "anything that brings you closer to the template helps" with the spoilers.
I'm actually asking a question here (not putting forth an argument)- I'm ignorant enough that I only have aerodynamic questions, not opinions.
