This has scipy as a conditional dependency. We don't do this anywhere in the codebase and at the very least we would need to make it a testing dependency.

I would believe that this interpolation functionality is already provided by the image extension (via agg), depending on scipy is likely a no.

Agreed - However, I'm not sure this kind of interpolation is even correct for plot_surface which I'd have thought would be more like pcolormesh and either use nearest or Gouraud.
