The decisions of some local communities is not compatible with definitions is some cases.

There are a lot of remote islands with similar population where the maximum classification used is tertiary or unclassified.

The general agree criteria for measure the importance is based on population of places. All examples shown in "assumptions" paragraph of the wiki are big/medium cities joined by a highway that crossed entire countries; that's not the point.

Well, before your intervention in Fildes Peninsula was accepted "de facto" the unclassified value, then the tertiary value is a intermediate of both positions and a just solution in case of disagree.
