Great answer and very good analogy. I enjoyed 3D a lot in many 3DS games, I got my best records in Pilotwings with 3D on. But it didn't work flawlessly which was annoying, if not distracting.
With the Dual Sense, we are talking about a technology beyond visuals, that sends feedback: sensations, informations, clues. It will surely be poorly implemented sometimes. Yet I have little doubt, based on so many previews I read, that it will be a game changer in many titles. Like, gameplay will be more satisfying with it than without.
