There were a lot of (lengthy) discussions about it on this list. I guess
the main advantage is that you specify a lake more precisely in physical
terms - it consists of water and islands inside the lake. Just using
higher layer tags for island is more of a hint for rendering software
and does not specify any relation between the lake and its islands.
