Zone's offer admin level functionality that may not be available to all users.  I don't think that Rackspace will expose Zones to it's customers right away, for example. By having Zones as an extension a client can detect whether zone support is available or not.

	It was my understanding that zones would be transparent to the user; in fact, we went to great pains to ensure that zone information was *not* available to the user. Clients would not need to detect if zones exist.
