Well it does and can. But then I suppose it depends on the arbitrary
restrictions certain vendors place on you.

GateD can with group type internal, IOS can't. GateD with group type
routing requires an IGP running. In this instance you aren't
running BGP as your IGP you are running ARP and static routes as an
IGP.
