If it has haptic feedback, you would be able to feel the buttons. Imagine force touch to speed up the fast forward.
So now I need to charge my remote too? Let me guess, USB-C?
Also, heptic feedback won't replace actually feeling where the button is blindly. Heptic feedback can help a fake button feel real, but it won't have coutours and the feel of contrastic materials (aluminum vs plastic). It won't help you know where the pause button is while watching a movie in the dark.
The fast forward force touch trick is cute, but nobody ever complained that pressing thr fast forward button was hard or awkward. Unlike force touch, the real button is predictable and reliable. One press to ff slow, two presses to go fast, amd three presses to go fastest. Press play to play.
I don't mean to imply there are no possible improvements that can be made. The remote today isn't perfect. Scrolling long lists is annoying, text input can be a pain, and the menu button and center button behaviors are unpredictable. I just don't think touch is the right improvement, and indeed it is the wrong one. Text can be fixed with a mic and speech-to-text, for example.
