Yes, a default route really makes only sense if the almost all of the
Internet (read: the whole internet except locally known networks) is on
one interface of the router.
And BTW since you mention ASs, then I conclude that you mean border
routers. And these are AFAIK (and IMHO in 100% of all cases) configured
by hand anyway which nets to announce, to accept and to route through.

Ah, I didn't realize that.
Hooray, we a (almost) technical reason for configuring unclean/fishy
netmasks;-)
