If StrictMath is still needed and could produce different results than

Why is it not always the case? I think that the answer is simply because
the StrictMath class was largely left unchanged and that delegating in one
way or in the other could then produce a difference when the strictfp
modifier was there, but is there a better reason than that?

Some targets (x86, in particular) have intrinsics (log, trig) that
are faster than StrictMath and also more accurate. StrictMath is not
about accuracy, but cross-architecture down-to-the-last bit reproducibility.
Whether we still need that reproducibility is, I suppose, something for
