Caves & Cliffs Backport by blackgear27 is probably one of the best caves and cliffs backport mod out there at the moment. While we wait for 1.17 to come out, could we get support for it in regards to the Malachite crystals? You say on the mod page you want the malachite crystals to be smeltable into copper when 1.17 comes out, and it would be nice for them to be less useless while we are in 1.16. Caves & Cliffs Backport adds in copper, and you said you want to add compatibility for other vanilla-like mods as well.

(I intend for this to be labeled an enhancement, but I'm new to GitHub. I'm not sure if that's your job or mine, cause I casn't find a button for it.)
