I would guess that it's because it isn't really helpful on rockets where you want performance. If your rocket's diameter is large enough for a boattail, you can just make the diameter smaller. If ypu need to launch a wider payload, you can just put the transition at the top.I see there are lots of advantages of a boat tail even if it adds some extra work on manufacturing. However, I generally see lots of rockets without it. Is there any other reason Im missing here?

I like turning boattails from 6061. Giant Leap used to market a boattail with an integrated "Slimline" retainer. Those are gone, but I still make boattails to fit over their standard Slimline retainers. I can't quantify that they improve performance, but they do look kool.
