Requested on Discord:

There's a recipe that lets you turn an iron nugget and a wikidium chunk into iron dust. It would be nice if the Mekanism machine you use to make steel took iron dust, and not just iron ingots. (It turns the ingot into enhanced iron dust, and that into steel dust.) It's a bit of a pain to have to make the iron dust into an ingot just to grind it up to make steel...

I have decided against this one actually... it's really not that much of a problem to just add smelt the iron dust first. Not everything needs to be simple ;-)
