I think a major purpose of this discussion should focus on assigning the relative "importance" of highway=residential and highway=classified once and for all. If we can come to agreement on what is meant by the two tags, we can better formulate guidelines that ideally will end up in the Wiki someday.
I know for me, there is confusion about it, and I bet I'm not alone.
