But it can be and is actually.

Well it can be harmful in many ways. It could contain heavy metals or other contaminants like arsenate. Minerals are easy to add to soils without using rock dust. Some rock dust may take a decade to become available to a plant.
I have some mineral deficiencies and use sulfates to replenish the soil. Sometimes as a foliar spray so it is quickly available to the plant. I have a manganese deficiency in my soil. Manganese sulfate in a foliar spray has solved the problem.
I'm all for using all types of rock dust, but I would not stop using fertilizers with complete trace minerals. Or apply chemicals as needed. To me I don't pay attention much if something is organic or not. Like sulfur to me is a chemical, and I will always consider it as such. Even the word organic to me has to do with carbon chemistry so Agent Orange is technically organic. I wish they would have used another word for organic in gardening, because it already has a meaning.
