> BTW, long ago Richard Taylor championed single brood boxes for making both lots of comb or normal frame honey so there is not much new under the sun.

During the comb honey era (late 1800s, early 1900s) single brood nest was the norm. Usually an eight frame one. Forces all the honey into the supers. Root championed extracted honey, two story brood nests, although the second story was called the "food chamber" with an eye toward winter stores. Farrar moved to a three story unit and promoted huge colonies as the best insurance against winter loss. With the prevalence of migratory beekeeping, one story colonies are back in vogue, lightweight, easy to move, but always in need of feed.
