The trunk issue is just a matter of selecting one level in the
road-priority hierarchy.  Being off by one is not the end of the
world.  Get the verifiable parameters right, name, surface, one way,
single or dual carriageway and trunk vs. primary or motorway isn't a
big deal.

The original classifications come from English highways so it's no
surprise that things differ elsewhere.
