Clarification of what I meant: Honey comb built in the supers, for storage, will (from my experience) almost always be built of drone cell size. Bees naturally do this because they can use less wax to produce fewer cells, which because of their larger size, will hold the same amount of honey. Simple efficiency! This will be done in a queenright colony and has nothing to do with laying workers.
Keeps who like to replace older combs in the nest, by using their newly built storage combs won't be able to use these because they will be used by the queen for drones and not for worker brood. [Unless, for some reason he is interested in raising large numbers of drones.]
If you "crush and strain" to get your honey, obviously, the size of the cells will be totally unimportant to you.
