If you're still shooting lead, or if you can afford Bismuth, I agree. But steel shot in 2 3/4" shells is a bit of a handicap. The extra payload of 3" shells helps offset that somewhat. That is about the only practical use for the longer shells though.
Inside of a certain range I don't think it handicaps you greatly (say inside 30 yds or so). Beyond that you do gain some by getting better pattern density, but I also think a lot of people have no business shooting at waterfowl beyond about 40 yards. I can also see where all those extra pellets would be beneficial for turkey hunting as well. It's the only scenario where I'll actually use 3.5" shells in my 12ga.
