Yeah, I think I had the same concern in the original review.

I don't know if it's a worthwhile optimization or not.  But if you can hack something together, it should be easy to run an experiment -- compile TensorFlow (or Eigen or Thrust) and use the statistics we already have to count how many extra vectorization opportunities we find.
