I think this is a misinterpretation — superdeterminism says that there is no true randomness in the function, not that the function is of any other particular form. The excitement is from the possibility that the function may be very simple (in Kolmogorov complexity terms), yet yield only one possible result for the state of the universe at each point in time. (Much like the process for calculating pi is simple and there is only one value for pi, but without knowing the process, there appears to be a lot of complexity or randomness.)
