According to the magic spec, Externalizable is what you'd extend if you
wanted to use something like PDF or XML as the serialization format. I
don't think Externalizable is easy to extend in a subclass (i.e., it's all
or nothing), but I'm not sure about that.
The writeObject method, on the other hand, is passed an ObjectOutputStream,
which provides the powerful defaultWriteObject extensibility mechanism, as
well as a set of convenient write* methods.

Isn't that what Externalizable is for? That way you don't have to remember
to make all fields transient. Or is there something in this magic book that
says that Externalizable is bad? :)
