Why do people ignore 1/4" backer?

I think most people associate quality with heft, something thicker or price? We normally use 1" TnG plywood screw and glue to the joist to eliminate bounce (always blocking for bath) and apply 1/4 Hardi-board on top for the tile to stick to. It normally works out perfect with the adjacent floor height. Due to various height of the adjacent floors, we sometimes glue Ditra directly to 1" TnG plywood and tile on top of that for bath floor to try and match the height of other flooring.
When we get into the baths, the 1x6 sub floor always goes and get replaced with plywood. I don't like sitting cast iron tub on top of the 1x6.
