Here in the west, many call these deeps vs mediums/shallow boxes.

As Lloyd says, its a good option for hobby beekeepers because of reduced
weight.  Many of our commercial folks use all deeps, so that they always
have a box for whatever's needed - no real difference between brood boxes
and honey supers.  Also, it cuts down on the number of boxes/combs to
extract; although it does increase weight per box.

Having said that, there are commercial folks who routinely use the shorter
boxes for honey supers.  That way, they know which boxes are honey supers,
and never bring the "brood" boxes into the honey house.  If they get a
diseased colony, they're hoping that the brood boxes have the worst
infestation, and that the shallow, extracted honey supers will be less of a
threat for re-infestation -- with thousands of hives, they don't keep track
of which honey super came off of which set of brood boxes.
