apart from the usefulness in routing (as there aren’t alternatives it doesn’t matter for routing if a road on antarctica is unclassified or primary, and usual time estimates would generally not be useful in this particular context and also likely more depend on the vehicle than the “road”), the scarcity of the grid which doesn’t allow for relative comparisons, I would tend to upgrade rather than downgrade, because the very few routes which connect something across significant parts of the continent, cannot be seen as insignificant as a tertiary function. Tertiary requires that there is also a primary somewhere, in the region (while this argument by itself could maybe also lead to many other “main” roads on small islands being considered primary, I think length also has to weigh in), in the case of the South Pole Traverse it is 1600km not comparable to any tertiary road.
