Blackstone Using a Blast Furnace

Since blackstone is the equivalent of stone in the nether, it's important that, like cobblestone, there is a way to get it with relative ease. However, there is currently no way to generate it.

My suggestion is that the blast furnace should have the use of smelting netherrack into blackstone, while leaving the regular furnace's recipe for netherrack to nether bricks untouched.

Not only is this suggestion in line with the design of the basalt delta, this method would also provide a new use for both netherrack and blast furnace, without creating any complicated method or additional blocks, unlike other suggestions for blackstone generation.
