I think we should err on the side of "preferred form for modification" 
rather than preparatory material.

I love having access to preparatory material, and I know from experience 
that it may be necessary for understanding and therefore competently 
studying, critiquing and building on a work. But forcing disclosure of 
preparatory material introduces problems of privacy and practicality. 
Many different works may emerge from a single set of preparatory 
materials. And do I have to spend all day scanning my sketchbooks just 
so I can release a work BY-SA?

Having the Blender file, or the layered image file, rather than the 
lossy video or image files is a very easy line to draw. Requiring the 
sketchbooks that I filled in coming up while developing those files to 
be digitized probably goes too far.

(I wouldn't use fashion as an example for copyleft, as there's currently 
a struggle to *oppose* the introduction of fashion copyrights in the US.
