The way they answered the question showed that they had already
considered this particular failure case and engineered their
implementation accordingly. That is good enough for us.

Incorrect origination of a default route is, after all, just one of the
essentially infinite ways our transit providers can screw up our
services. Therefore it would make no sense to me to entrust the
delivery of our business critical packets to a transit provider, yet at
the same time not trust them to originate a default route reliably.

If we did not feel I could trust my transit provider, we would simply
find another one. There are plenty to choose from.
