I mentioned this here too.

When it updates to 1.16 can you add auto mine for ancient debris I mean it’s pretty self-explanatory it would be a bot mode option under auto mine section and you just choose ancient debris.

Given that Baritone has the ability to mine for any block, you would assume that the ancient debris will also be added, wouldn't you?

Ok yay 😁

I think they meant an option in the AutoMine menu, like beside diamonds.

This shouldn't be in the baritone repo, baritone automatically supports any block, it's not manually hardcoded what works and what doesn't.
