Water with Distance Field Shadows

Does anyone know if there’s a way to get Distance Field Shadows to work on the (surface of) the new Water system?

I have very large objects that need to project a shadow on the sea surface.

So far it seems that only CSM shadows work, while “Inset Shadows For Moveable Objects” and Distance Field Shadows have no effect on the water surface.

Is this something that’s still in development? I suppose so.
