Drywall Backer Boards

The traditional way to install drywall is to terminate butt joints on a stud or joist. An optional method is to use a contoured backer board allowing attachment of butt joints at mid span between framing. The contour is supposed to pull the drywall edges inward to mimic a tapered joint. The width of the backer board allows attachment away from the very close edge of the butt joint. The subs in my area have never heard of this method. I would appreciate any comments from anyone who has used a "ButtBoard" or a "RockSplicer" backer board.
I'm using 1/2" drywall on walls and 5/8" on ceilings.
