I agree is some cases but not in others. Incorrect tagging that can go unnoticed is worse than a lack of tagging. For example lots of roads tagged with incorrect surface, speed limit, and access values would be worse than if those attributes were missing. On the other hand if the roads were correctly tagged, but the geometry was inaccurate (while still being topologically correct) then I consider that an improvement over no roads at all.
I don’t believe I or anyone else has suggested importing this data without review. In fact a review has been done. Although it apparently didn’t meet your standard.
