Its diagnostics and output are a little rough, depends on the standards for
contrib I guess.
I'll maybe ad some slightly better messages and a warning about the winding

Yes I think this would be very useful. Blender is very precise for 2D
layout and has a nice quick interface, but
breaks down when you try to do 3D set operations (its art-oriented after
all, the results *look* great usually...).
So its a good match with OpenSCAD.
