The default route is the one you use if no other route matches a destination. If you allow multiple "defaults", how do you pick which one to use for a given packet? You need a whole new mechanism to choose among default routes. Why not simply use host routes? Disclaimer: I may be biased here, because I think implementing multi-homing at the transport layer (like SCTP tries to) is a bad idea in general. It's a network layer concept, reimplementing it at the transport layer gives you no new capabilities.
