Essentially all languages allow manual seeding: almost none specify guarantees with regard to RNG behavior. I'm pretty sure this is because determinism of a given process important (everyone who does simulation needs that), but locking into potentially bad RNGs for the language or library itself, in fact specifying them, is a really bad idea.
