You are right, a lot of people overreact through ignorance of how plants even grow. Also those who scream in Amazon reviews of "OMG this clings to the scoop and container it's got metal contamination!" Hey dipshit, any fine powder acts like that when exposed to electrostatically charged plastic in low humidity, use a metal teaspoon or drop a magnet in there and see just how "magnetic" it really is. It's amazing how many so-called anons don't even remember grade school science. Most of those heavy metals are not even magnetic to begin with.
