[openstack-dev] [neutron] Why is "network" and "subnet" modeled separately?

Here's a neutron implementation question: why does neutron model "network"
and "subnet" as separate entities?

Or, to ask another way, are there are any practical use cases where you
would *not* have a one-to-one relationship between neutron networks and
neutron subnets in an OpenStack deployment? (e.g. one neutron network
associated with multiple neutron subnets, or one neutron network associated
with zero neutron subnets)?
