I think it's a better solution to the problem compared to what Minecraft does (see the bedrock article) because it is more realistic. In "real life" you'd be able to keep digging as deep as you want on the Moon until you reach the center, because the Moon has no magma. But all you would get is more of the same: more rock and some minerals here and there.

So they let you dig as much rock as you want. I think that's a pretty neat solution to the bedrock problem.
