I'm still wondering, if we look at the classical determinists in the history of philosophy, such as Spinoza, d'Holbach, Laplace, etc – were they superdeterminists or "subdeterminists"?

If the mainstream of historical determinism is in fact superdeterminism, then the term is a bit misleading, because it makes it sound like physicists are coming up with some new idea rather than just restating one that has been around for centuries (maybe even millennia).
