> For instance, pressing the pedal on a digital won't give you any feedback from the felt rubbing on the strings. Most classically trained teachers would recommend an acoustic over this fact alone.

I wonder if there would be a market for that level of emulation.

For example in the car sim scene the higher end braking pedals measure not just the movement but also with how much force it is pressed (force needed for brake pedal is nonlinear with pedal movement), so you have more control over it (easier to control force of pressing compared to absolute movement of the pedal)

> An acoustic grand also has more opportunities to change and shape the color of the tone. A technician can make the piano warmer or brighter for example.

Yeah nah. Digital pianos often have more than one sound to choose from, let alone more advanced synths. If we're talking sheer variety of sound digital has no limits, even if your particular device does there is always option of connecting it to PC (althought no doubt archaic MIDI gonna lose some of the detail there)
