On the other hand, it's nothing like the track frame which had a horizontal top tube, non-Superset 2 frame, no rack bosses, rear track ends without cut-outs and a non-Unicrown fork with significantly less rake, that placed the wheel much closer to the down tube.

In my experience, the fixie/SS fraternity tend to be minimalists and removing braze-ons is quite common among them. The Volpe of this era had vertical dropouts, providing no axle adjustment to the chain. It would require either a tension accessory dropout replacement or tailoring the gearing to provide proper tension. So, the changes make sense, even if they do seem a bit extreme to some members, who might argue that it's easier to find a more suitable frame.
