I think you need a unique set of circumstances to make the small base dies necessary.
1) A semi auto or lever/slide action without the primary camming action of a bolt action.
2) a minimum dimension or "match" chamber.
I have both of those in my M1A Supermatch. Small base dies work well in it. I believe that there are not a lot of different vendors making them because not many folks are in that boat.
By the same logic, why does Lee make "U" dies when no one else does or the Lee Factory Crimp die or the Redding Profile Crimp Dies or even the Lyman "M" dies.
Each company has its specialties it plays in.
