Er, this fact is mostly unhelpful: there is no "gateway" — there are
zero-or-more gateways, depending on the route on the server, which may or may
not get used to communicate to any given destination.
A number of our machines have two or more gateways, since they have multiple
paths to other networks, differentiated by route priority and/or manipulated
by a routing protocol.
So, a simple "gateway" fact is essentially meaningless for our network; this
is probably true of at-least-some machines on at-least-some large networks.
(So, while your fact is meaningful, it isn't a generic "gateway" fact :)

This can return multiple results, trivially, even on a simple network where
you have multiple definitions in /etc/network/interfaces; it breaks in the
face of network mapping, or of having two NICs with gateway statements.
