I would not consider the position in the OP as "aerodynamic". Sure, more leaned than a Dutch town bike, but much more upright than a racing position.

I think this "in between" position is perfect for touring. Comfortable enough for long distance, but It is great to be able to get into a more aero position when you are going long distances into a headwind, let me tell you. An upright position would be downright annoying.

If you find the position on an average touring bike too be uncomfortable, I am sure you can tweak it to be a bit more upright. Those "Butterfly" touring handlebars can help a lot to achieve that. But I would never take a Dutch town bike on a long distance tour for example.
