Yes, it's difficult to tell if the clamp has the padding one would expect a seat post clamp to have, and if the clamp can be secured with a torque wrench (just got my first one - for the carbon fiber seat post on my bike).
If those issues are properly addressed, this could be an improvement over attaching a seat bag, as seat bags are entirely supported by the seat post while the Tailfin distributes some of the weight to the bottom of the frame.
