I worked a project as recently as 2009 where we tried to connect two
6509s together over a tunnel interface and wanted to extend Area 0
across it and couldn't because it was a limitation of the version of IOS
we were running at the time.
That forced us to use isis.
It was a decision based on pragmatism rather than design choice; and we
were a small operator, too. The choice of an interior routing protocol
really doesn't have much implication for small operators.
