     given the normal meaning in computer science of the word "default".

     One default route per source prefix in use makes perfect sense, in
 view
     of the need for address pair selection and ingress-filtering
 avoidance.
     (When I think about it, a default route even makes sense for a ULA
 prefix.)

 No, multiple default routes make sense even when they're not source-
 specific. For example, they make sense when you have two routers and one
 of them can go down. Remember that a route includes a next-hop, and that
 RFC 4861 defines a default router list (which is a list of possible next-
 hops for the default route).
