so we can just do the opposite of mining and restore 'density' to voxels, but this doesn't solve the problem of making voxels where they've been completely mined away to a 'density' of 0. It can be done, it'll just need someone to sit down and figure out the best way to do it. Unless we hit any major problem we should be able to add it eventually. If you're keeping an eye out for it in updates, we'll likely refer to it as 'Voxel Painting'.
