Yes, this is defensible as well. From a perception management perspective, I think its good to deliver batches of related features together, because users are already going to have a hard time remembering what was added in 12 vs 13 vs 14. So remembering “switch on long in 12 and switch on float in 13” is hard, but “all the new switch goodies in 13” is easier. That’s not a hard and fast rule but its something to put in the decision mixer.
