Not going to happen because that would be much more expensive, and it would even be more embarrassing than Apple quietly discontinuing a product.
Also, I wonder what the environmental impact differences between natural leather and whatever plastic Apple used when it comes to manufacturing these cases and their end of life at a landfill. I suspect natural leather would be much more environmentally friendly. I wonder if the plastic Apple used isn’t so bad because they designed it to deteriorate rather than around forever. That could be causing the durability issue, but that’s just speculation on my part. These cases might be just as bad as other plastic items.
