I've seen such large networks in private industry (and governements, not  
just the US) several times.  And IPv6 has been designed (poorly, it would  
now appear) for huge "LAN"s -- LANs are supposed to be /64, after all.

One of them "had" to have such stupid large L2 domains because they used  
RIP (v1) EVERYWHERE. (all networks had to be /22's)  They made a god  
aweful mess trying to switch to OSPF, got fined by a three letter  
regulatory agency, and are probably still running RIPv1 to this day.
