Actually looks like we need to find Ton (or have Toni poke him hard when 
he sees him).  Daniel removed it after he discovered it wasn't being 
used anymore:

(comment from blender/source/blender/makesdna/DNA_meshdata_types.h, v1.9)

- some python code accessed the MDeformWeight data pointers, but
    did so in a completely wrong way, I am positive this code could
    never have worked (or maybe things changed during tons refactor),
    regardless it wouldn't work now... will test later.
