The problem with that is that when copying messages between mailboxes they would have to be actually read and written entirely, rather than a) with sdbox it can use a hard link() call, b) with mdbox it can update 3 indexes. Copying is a rather common operation since clients often move messages to Trash, so the extra writing would be a bit wasteful.
