It is useful for systems with multiple interfaces, for example a desktop
with wired and wifi, and different preference default routes out both
(so if the wired goes down, traffic can still go out over the wifi).
Anything acting like a router also needs this behavior, typically in
conjuction with dynamic routing protocols.
