Richard - why are we changing roads to unclassified?

Comment from Richard
Hi Clifford - highway=unclassified is the standard OSM tag for a minor rural road of reasonable quality (assumed paved in a developed country), as well as those with more of a connecting role in urban areas. The introductory paras at http://wiki.openstreetmap.org/wiki/Key:highway explain it well.
The TIGER import assigned all geometries of class A41 to highway=residential. In many urban areas this was a good fit, but in rural ones it was (and continues to be) contrary to standard OSM practice.
Much of what the import tagged as highway=residential is more accurately highway=unclassified, highway=track, or in many cases entirely fictitious - there is no road at all. This means that it's difficult to use unreviewed highway=residential in rural areas with any degree of confidence: routing over it may equally send you up a beautiful paved road or into an impassable quagmire. See https://twitter.com/marcpfister/status/601782213688987649 for a typical result!
Assigning roads to the correct category that would have been used had they been mapped from scratch, rather than the arbitrary highway=residential mapped to the A41 class, therefore aligns with OSM in the rest of the world, results in more nuanced cartography, and lets data consumers make better decisions about which roads to choose.
