I like this idea.

Let's think about it from the other direction: if a user wants to shuffle all the elements as if it were 1-d, as you point out they could do this: shuffle(a, axis=None, independent=True) But that's a lot of typing. Maybe we should just let this do the same thing: shuffle(a, axis=None) That seems to be in keeping with the other APIs taking axis as you mentioned. To me, "independent" has no relevance when the array is 1-d, it can simply be ignored.
