I have the Lootr and Spawners Unbreakeable mod installed where neither explosions nor breaking can break these blocks, but your quarry breaks everything, it does not check whether the block can be broken or not. It would be cool to add a list of tag blocks that the quarry cannot break.

Quarry seems to be only checking alexscaves:unmovable tag which holds only #minecraft:wither_immune tag.

Some blocks have durability set in ways to signal unbreakable. I think -1? There's no tag named unbreakable as far as I know. I think adding a check to Quarry code for negative strength should do it.
