Yeah, it's a tricky question, especially when it comes to updating (imo the initial import was fine, though some people disagree). I like the current assisted approach of letting you turn on a TIGER 2012 overlay in the editor, and/or use tools like the "TIGER 2012 Battlegrid" (http://maproulette.org/battlegrid/ http://maproulette.org/battlegrid/) to find where OSM/TIGER differ. So far based on some limited experience fixing OSM based on those tools, it's a good decision imo not to do it in an automated fashion, because when I've found OSM/TIGER differences, it was about 50/50 which of the two was right.
