I label my drone frames, because they can't be used for a nuc for laying space with a new queen. Those are not useful as worker cells! But... for a full sized hive, they are fine as 1) expendable heat source this time of year, AKA drone brood, and 2) eventually honey storage for winter. Having drones is good in my book because more drones means all queens have a better chance at success - and those queens will eventually lay drones for your queens, down the line... The queen will likely refill with drones once or twice more, and those may not open up until August. But they will open up in time for winter honey storage.
