In this type of situation, the national convention should probably be
revised to better match the more general guidelines.
An example: Madagascar seems to be following a classification similar
to mainland France, where trunks must be divided and have 2 lanes per
direction. As a result, there is no trunk road network there. Yet, the
two largest cities (Antananarivo and Toamasina) are linked by a paved
road in good condition.  It surely could be trunk if one applies
the same logic that promoted to trunk Iceland's Ring Road,  which
was partially unpaved until recently and is still mostly a single
carriageway with 2 lanes (1 per direction) without a shoulder. But
that main road in Madagascar cannot be trunk according to Highway Tag
Africa and the national guidelines.  Google and Waze display it
(and several others) using their types equivalent to trunk in OSM.
