Add white FreeSurfer surface to derivatives; replace smoothwm?

[effigies]

I can't remember the exact reason we chose to use smoothwm instead of white, but white is the fully reconstructed and processed surface. smoothwm is the initial surface post-topological fixing, if I understand it correctly. For all FreeSurfer and Workbench processing (post-recon), white is used, not smoothwm, so we need to provide white to play nicely. Is there any value to continuing to produce smoothwm?
