How do folks get surplus honey supers with top entrances? I tried these because to the advocacy of the proponents, but the brood nest moved to the top. Most hives were 3 or 4 stacks (deep, deep, medium) or (deep, medium x 3). In all cases, the bottom of the hive was abandoned (during summer dearth), as the brood nest moved up.
Practically, it seems difficult to get solid honey supers that can be lifted off, and can be cleared of bees easily. I don't want to unstack whole hives and poke through frames looking for brood-free, capped honey. My bees are defensive, aggressive in the late summer, and unstacking a hive was asking for unpleasant chaos.
