Though, in WoR: Dust, Salem said "Despite working, fighting, and even turning a profit with it, humanity has still yet to understand how Dust came to be, and more importantly, how their involvement with Dust will ultimately change the world of Remnant."

We still don't know what she meant by that, but how their use of Dust will change Remnant is apparently more important than where Dust came from.
