also, doubletaps in taiko aren't required afaik, you simply get more points for doubletaps on the larger notes than singletaps, and combo remains the same between single and doubletap.
why would doubletaps not aid in tapping the "correct" rhythm moreso than single keys only? doubletapping emphasised beats could be quite fun, assuming it matches the music.
