If you want all your body weight on your arms, then yeah, sure, it'll be good for you. You'd have to have a frame with really slack, I mean like high 60 degrees range for a zerosetback to work without putting all your body weight on your arms.
72~74degree seattube angle is normal road and touring geometry, but track frames usually have something steeper and by going with a zerosetback you make it even steeper, forcing your body very far forwards. This might be good for aerobars in a tri fashion, but it's hella uncomfortable to have that much of your body forward and on the arms instead of the legs for any decent distance.
Of course, differences in core strength make a difference, but I'd like to see anyone try a century with a zerosetback seatpost and a frame that has 75~77 STA.
possibly, but what if one has a 73ish seat tube but wants an aggressive setback from the bb. they could have it scooted far forward on a typical seatpost, or have it close to the middle with a zero setback.
granted it's almost purely for aesthetics, but cyclists are all about their look
