Crafting recipes using blackstone

First of all it's not a bug, but for some reason i can't change the tag to improvement/ QoL advice.

In the latest snapshot some recipes where blackstone is used in replacement of cobblestone were added, but for example since grindstone uses a stone slab, there's no way to craft it in an only nether challenge.

I know grindstone recipe doesn't look like something important but it in this kind of situation unlocks the whole enchanting branch since you can disenchant a soul speed book to craft an enchanting table with it.
