I think that was the idea. And that honey is inevitably going to be in brooded comb, and if the hive is authentic, that comb will be stuck to the sides of the boxes and to the tops of the bars below. Therefore, it's all going to have to be crushed for extraction with the loss of all the comb.
It's no-nonsense beekeeping at its "finest" and
hard impossible to justify as an efficient, honey-production method when compared with regular beekeeping as we all know it.
But for me, one of the attractive things about keeping bees is the jeopardy involved, and you get plenty of that with Warre done properly.
