I don't think I expressed any "opinion", the functionality is useful but probably not the *place* for this since vgroups are by definition a 0.0-1.0 value. Blender has custom vertex data available in the C API, but everything is so hardcoded that.. good luck using that in a modifier or anywhere else. I keep looking forward to the nodetree and for now I'll go with not enabling this where it doesn't belong.
