So you still haven’t clarified exactly what you meant here…
I will presume that you meant a way that joins a settlement to the road network can be tagged as Unclassified (or higher) unless it is only passable by an offroad vehicle, in which case it will be tagged as Track. As this is something that can only be accurately ascertained by actual surveying, armchair mappers can tag such a way as they see fit, unless the way has already been surveyed (source marked as GPS or similar) in which case they shall not change it from a Track if so tagged. And, if after surveying, a way is found by an OSM editor to be tagged as Unclassified when it should be tagged as Track (offroad vehicle required) then the tag should be changed to Track.
OK everyone?
You keep trying to say that these tracks into villages are being tagged as Track because of a want to ‘tag for the renderer’. That is not correct - and, unless you want to actually get out there and survey these ways, you are in no position to judge. You, seem to think it is acceptable to ‘tag for routing’. That is no better then tagging for the renderer. After surveying, a way should simply be tagged for what it is - ie. it’s physical attributes considered along with its function. Otherwise there are falsification and safety issues, etc.
Note, whatever happens with renderer support is irrelevant if the way has not physically changed.
