I'd be very careful with such fallbacks: DNS servers (especially in companies) tend to define their own local hostnames, and if we'd automatically fall back to 8.8.8.8 in such cases, those hostnames would suddently vanish from view. 8.8.8.8 is fine as fallback if no other DNS servers are known, but if we know one we better do our best to talk to it.
