Yes, I also know about Chase Bliss pedals, I think they use midi.
It's been done but it's not really "mainstream" and standardized.
Imagine a standard where all your pedals etc can be recalled / automated from another (central) unit, with a protocol that the hardware can adapt to, motorized faders, rotary faders with leds, or basic components etc.
Maybe that's what Wes Audio is doing with the gcon protocol that has been linked below.
Motorized faders and rotary encoders would be nice, but also overkill. Most of my gear, even analog like Moog Sirin supports MIDI Program Change messages, so this already works today.
