if you have a single upstream, it is important to accept a default.  If
you don't, you will lose connectivity to other customers of the upstream
which, for traffic engineering purposes, have tagged their prefixes as
"do-not-advertise-to-customers".  This happens regularly on tier1
transit providers.
