We have Deepslate as an option, but could Cobbled Deepslate be added to the compressible blocks? I hardly ever mine deepslate with silk touch since it's normally useless in the raw form.

I will try to add this in the future, right now I'm quite busy.

I have added Cobbled Deepslate. Thank you for your suggestion. I will close the issue now, due to the new feature implemented.
