Dirt full of water is not a negligible mass, especially as the total mass will vary and the center of mass will shift around.
But the real problem is water. One of engineering's most important lessons is "everything leaks". I think all of these projects are just a recipe for mold intrusion as the water leaks out of the soil box and into the rest of the building.
