Yeah I would revert, nothing in that commit seems important and changing road classifications in just one part of town without responding to comments is grounds enough. Not really vandalism, but not a great edit either, and it caused some problems.

Actually, on parts of that edit I'm wondering if it's from http://wiki.openstreetmap.org/wiki/StreetComplete ? Why else add surface=fine_gravel and a name to a 5 m long footpath...
