Ocp 3 riser in the future?

Seems like 2x MCIO x8 to OCP 3.0 x16 riser cable could be made

I've recently found these adapters for sale on the internet:

They are branded as KCores, however, I haven't seen any schematics or even documentation on those around (I'm curious about what those dip switches do, what the specs of those are, etc). Is there any more information available about those?
