I believe initially it was dropped into route-maps to deal
with situations involving having three different ASes
share a broadcast LAN in Washington D.C. as an internal
link.
(AS 1239, AS 1790, both sharing a single IGP instance, AS
1800 with a different IGP instance, to be specific.
Running two independent iIS-IS instances on a single wire was fun too.)
FSVO "valid use", but it did make things work.
