The value proposition of deep learning is to eliminate these kind of hand-coded features and to discover the features automagically.
Yes and just to clarify - this seems like an indication that however useful, deep learning can't follow through with that promise. And I think the ability to do this the key thing - all the approaches work at some level but without this "automagicity", each become hostage to brow-wrinkling experts who become the only one to understand the black-magic of algorithm tuning.
