Users have also seen about 30% performance boost with MKL, now with the latest release we are dropping support and forcing to use another experimental which we know(from all the discussion during the release) that its not stable. Also OpenBlas=MKL does not bring all the features for MKLML and MKLML will have a smaller sized library per this response by a Intel member https://github.com/intel/mkl-dnn/issues/102. IMHO this is not a good practice, I also wish that a discussion happen on dev list before we drop support, so more people provide feedback.
