The tagging scheme should have a clear intention to facilitate rendering and routing. Then renderers and routers know what there is, so they can decide how to handle it.
If residential area means that road class is highway=residential unless taggted otherwise, that should be made very clear. At the moment, I don't think it is clear, and road tagging in residential areas in Nederland certainly does not follow this principle. If the scheme is adopted and very clearly documented, I could adjust the residential road tagging in my village (pop 25.000) in a couple of hours. Most residential roads now are tagged as unclassified, I just have to list them, determine if the default fits, then retag them as highway=road. The problem with such a default of course is: if the area is altered, roads may (and will) unintentionally change because suddenly the default applies or no longer applies. Also, wouldn't renderers and routers will have to deal with roads crossing the border of a residential area suddenly changing types, without a node to tie the action to? If there is no general agreement: the bulk of residential roads in my area will remain 'unclassified', in the wrong sense i.e. no classification.
