Agreed. In Nederland, I think most mappers will agree.

It's just that a gazillion roads and streets have been tagged as
unclassified based on an import assumption that unclassified means no known
classification. Seems like a candidate for automated correction but...
another gazillion roads actually are of class unclassified.

Meaning that correction is a herculic task and a huge incentive is needed.
Since there is little impact on rendering and routing, no crowds are lining
up to take this on.
