Protective cases for Surface Pro 8 (non-Microsoft)?

For all the other Surface Pro devices one can find on the market a wide variety of protective cases that include a kickstand. The native kickstand for Surface Pros has always been small, flimsy, and--frankly, almost pointless--so this type of case has always been essential for making the Surface Pros really usable off of a desk. 

But I don't seen any of these for the Surface Pro 8, which is about to ship. Why not?

My understanding is that it has the same width and length as the Surface Pro X, but is 2 mm thicker. So it should be easy for the makers of these cases for previous devices to simply adjust slightly. Yet, there's nothing available. Where are all the vendors that normally appear to sell these things?

And, yes, I know that Urban Amor Gear claims to have something, but it's not a full keyboard-compatible case.  Kensington also has something, but that just uses the native kickstand, so it's pointless.
