   > Now that some of the kernels actually support dictionary encoded arrays natively, I wonder if it would be possible to maintain the dictionary encoding as part of the coercion rules (rather than coercing the output to a primitive type)?
   
   For mathematics numerical kernels, the returned type of two dictionary input arrays is primitive array. So for `mathematics_numerical_coercion`, this looks still correct.
