Should you wish to eg find the area under a curve you would also want to avoid clumping, which clumping is a characteristic of a good PRNG. For such applications a Quasi Monte Carlo sequence of D-dimensional Halton sequence vectors is preferable, providing good spread within the set lower & upper limits & avoiding clumping.

For eg crypto purposes, QMCS is not so good.

In short, there are some uses where real randomness approxination is not the chief criterion of efficacy.
