All Deepslate Ores need to smelt

hello mojang! I got a Idea while i was watching some minecraft snapshot streams! so, in the new snapshot, the deepslate ores behaves like original ores, and that feels a bit useless, and maybe it will be more interesting if all kinds of deepslate ores need to be smelt? the deepslate ores are harder to mine, and should make sense that they need to smelt for getting the the ore itself. And also make iron and gold ores dont need to smelt because it is weird. 

(bonus*: deepslate diamond ore's texture is messed up! its 1 pixel to the right <3)

thx for this incredible game!
