I know the process is there, but I really, really doubt it does anything else than just uses OpenSCAD code to render the mesh, as FreeCAD can also deal with meshes. I think it would be pretty unlikely that the FreeCAD devs would have implemented such a rendering system based on OpenSCAD.
From my quick tests, it seems to rebuild the OpenSCAD objects using FreeCAD part workbench primitives.
But I also quite quickly found examples that don't work. I don't know if that's the import not being very good, me finding weird examples, needing to install more libraries, or PEBKAC.
