I don't know. I could see companies like Carver, Mc, Parasound, Bryston doing this here... but have no clue whether the numbers exist for a business case.
One tier down (Sony, HK, Denon, etc.) certainly have the numbers of potential customers and the scale to fund this... but again, not sure if there's any money to be made.
It's funny that, for all Western societies'/business' talk about environmentalism, the only thing that seems to come out of it is a replacement program (turn in your old gear for credit for new gear) that involves shipping old boards to be shipped overseas to be recycled by children (a bit of hyperbole, but that's how it turns out at times).
