I think most attributes of the templates exist "for historical reasons", i.e. they are copied from another Minecraft wiki.

An item is not renewable only if there is absolutely no way to produce it infinitely in a finite world. Mithril ore is not renewable because it doesn't grow, it can't be crafted from renewable blocks, no trader sells it, and no mob drops it.

I'd support a removal of the tag. In the process we could also add new more meaningful tags.
