They could just not load (or even ship) the 32bit libraries unless they were needed. My guess is they don't want to develop and maintain 32bit versions of all their frameworks, especially newer features like drag&drop. (For the hardware part I don't know enough to say whether or not keeping a 32bit armv7 mode around is costly?)
