So is anyone trying "Opening the sides" of the broodnest?

Basically, "Opening the Sides" is inserting a new frame between the outside edge of the broodnest and outer storage frames. (Can be done to both sides at once.) It's for those who don't have spare drawn comb. To have bees drawing out comb before swarm season, with little impact on the broodnest. Using the excess nectar to build comb, rather than backfilling the broodnest.
