Well, yes, but the same kind of thing is trivially done on
a Cisco, and it would be nice to be able to do it on NetBSD too.
# Net 10.0.0.0/8 is reachable via interface Ethernet2/1/0;
# just use ARP.
ip route 10.0.0.0 255.0.0.0 Ethernet2/1/0
# Default route is to 10.1.2.3. Use recursive lookup to figure out

ip route 0.0.0.0 0.0.0.0 10.1.2.3
