Keep in mind, though, that the difference between a standard post and a zero setback post is commonly 25 mm or 1 inch. You may end up on the other side of the middle, i.e. behind the middle instead of in front of it. Not much gained if that is the case. Also reports of a "support" issue with a forward or backward saddle are very rare. And if there is an aesthetic issue, it is pretty much all in your head. More adjustment capability would be valuable if you need it, but if the saddle is in the right place now, what good would that do? Remember that zero setback posts were not (readily) available back in the day and folks did just fine either in front of or behind the center line of the rails. No one gave it any thought.

I agree that the Thompson is a great post and easy to adjust, but if a change doesn't get you anything real, what's the point? If you need it, you need it.
