I don't know, and neither does anyone else at this point, to my knowledge. What's the rush? Let geologists digest this new idea, and decide how worthwhile it is. Maybe it's a good theory, maybe not. But either way, the fact that one theory might require large changes doesn't automatically mean that some other theory, in a whole other field, will also require large changes someday. Maybe it will, but there's no way to know that from this thing.
Science is fun, and sometimes helpful.
