Interesting thread ! Living in central NY the weather here isnt dependable enough for me to rotate the hive bodies. I have always done that to give the queen room to lay eggs upward. Also to hopefully keep the brood chamber from becoming honey bound which to my understanding is why they tend to build swarm cells. As I understand it the queens arent laying fast enough at this time to run into the problem of her running out of room to lay . However when she does go into high gear I`d like to depress any tendancy to swarm.
That said I have also heard/ read somewhere that a laying queen cannot lay fast enough to fill ten frames of brood (both sides) without some of the brood hatching before she gets the box full.
I will continue to rotate (usually in mid april) mostly out of habit and when I decide which hives are going to be split and which might need to be requeened.
