I absolutely agree about preserving user contributions. For any given segment in the Virginia RCL Shapefile, there are any number of ways in OSM that make up that segment, with varying attributes. The reverse is possible as well. Merging this won't be easy by any means. However there's no reason we couldn't start importing (sooner) in areas that haven't been edited since the TIGER import
As for RoadMatcher, though I haven't played with it yet, I don't see how OSM attributes are lost, it's just that you have to map from OSM->Shapefile->OSM. Remember, I'm just broadcasting my interest, I have a lot of learning to do.
