   On one hand, there are existing MXNet models which would require hyperparameter tuning to be done again if this change is implemented.
   On the other hand, being inconsistent with PyTorch and other deep learning frameworks makes it harder to port models and the subtle differences might result in slight differences in performance.
   Even though having an additional flag to switch between old and new behaviour definitely adds to complexity, I am not sure that it is not worth it.
