Frame interpolation in MetalFX

It would be quite helpful if there was frame interpolation in MetalFX, similar to what NV and AMD are adding to their upscaling technologies. I have found MetalFX temporal upscaling critical to a real-time ray traced application, and frame interpolation could halve the compute cost, letting me try more expensive RT algorithms. I am hoping this technology will debut at WWDC 2023, if not then maybe during the winter round of OS updates.
