Unfortunately, blendshape weights are array attributes of type float, which
the docs say not to connect the parents. If they were float array
attributes, then you could connect the parents. Although I have been able
to hook up the targetWeights blendshape attribute to other nodes to take
advantage of the multitarget painting, I haven't been able to connect it the
other way around for some reason.
