It's not really possible to use it "incorrectly", AFAICS. Any value you
might pass to it will result in a specific new seed value. Nowhere is
there any guarantee of what the mapping is, and it's obviously
impossible to guarantee that the mapping is one-to-one, so any user
assumptions about what a specific seed value might "mean" seem broken
regardless.
