As a practical matter, if they're using the answer for a security baseline, they're doing it wrong - they should be planning that based on the assumption that their traffic *will* ride the rails of the commodity Internet (due to outages or whatever). Similarly, if they're looking at it for performance/latency, they need to fix their assumptions - your direct peering can be slow and congested, while there's actually a longer but faster path through someplace else....
