The layout is most likely going to be different anyway, isn't it? We don't know what has gone on in the past to get the FS into the current state.
But now we have more information than we did when the file system was originally built.
We don't have an extent based interface do we? So we can't say "I know this file is going to be X bytes in size." But if we accomplish nearly the same thing by a quick copy like this, what's the harm?
