No, this was not an automated edit at all. I made sure to check the highways before publishing them, since some values of road=* were typos (e.g., road=unclasified). Also, the fact that a road is unpaved doesn't inherently mean it can't be a secondary road (I just read the article for track roads on the wiki). Any locals who know the classification of these highways are free at any time to correct the classification. I changed most of them to highway=road because I could not determine their classification by looking at their tags (i.e., road=rural road). Also, marking them with highway=road alerts QA tools to (hopefully) alert users about what happened.
