We would need a rule for when to include the base in the pickle and when not to. Otherwise, pickle.dump(view, file) always contains data from the base pickle, even with view is much smaller than base. The safe answer is "only use views in the pickle when base is already being pickled", but that isn't possible to check unless all the arrays are together in a custom container. So, this isn't really feasible for NumPy.
