It is a good idea to set up the default route to one of upstreams when
you set up filtering. This saves routers' memory, but leaves your
connectivity fine. You can even accept 0.0.0.0/0 from several upstreams
with different localprefs to keep channels back-up working.

P.S. I don't believe backbone carriers who don't have upstreams at all
need to conserve some extra kilobytes of memory ;)
