It's quite possible that a user has created a function (by mistake or
deliberately) that gives away the hash of an arbitrary string. We haven't
taught developers that (s)he shouldn't disclose the hash of a string.

hash("") should return something constant that doesn't reveal information about
the random seeds. 0 is an arbitrary choice that is as good as anything else.
hash("") already returns 0, hence my suggestion for 0.
