My only concern with the scrubbing applies to bannered routes (routes with the "modifier" tag); we've been going back and forth on the proper tagging for seemingly years now, and while I think the proposed scrubbing conforms with the original intent under the tagging scheme, the generally agreed-upon (by everyone except NE2, at least) tagging seems to be as documented at: http://elrond.aperiodic.net/shields/supported.html
"The rendering expects data tagged according to the documentation on the wiki and further refined based on discussions on the talk-us mailing list. In particular, two things are worth knowing: "* The value of the ref tag on the relation must contain just the route number, without any network information. The relation for Interstate 5 should be tagged with network=US:I, ref=5. "* Variant routes (alternate, business, truck, etc.) must be tagged with the variant in the network tag, not the ref tag. (The variant text should also be in the modifier tag, but this rendering does not depend on its presence there.) Thus, US Alternate Route 1 would only be rendered if it were tagged network=US:US:Alternate, ref=1." Since this site (http://elrond.aperiodic.net/shields/) seems to be the only real consumer of route relations at the moment (we're not sure if Mapquest Open is or whether it's just running a bunch of ad-hoc data fixups to make its shields sensible), I think it makes sense to follow the guidance from that site at least as far as deprecating "modifier" in favor of making variants part of the network tag. However, the CR tagging changes suggested here seem fine to me.
