          <div>I would guess that there is some population of the user
            base that would like to track the per-iteration feature
            weights.</div>

            (un-optimized) implementation would be place a NaN value for
            a feature once it is eliminated, so that a numpy.ndarray can
            be returned and immediately dumped to matplotlib.pcolormesh
            or other visualization routines in various libraries.<br>
