Same as any edit, it means "I've improved this in some way." Given the vast array of things we can do to improve a point or way there is a lot of room for variability. Given a TIGER interstate junction, is it reasonable to: add nodes to the ramps to improve the curves; disconnect the node at the overpass and create a bridge; and split the way into dual carriageway, all from Y!WMS and call it improved? Certainly. Could it still be wrong if the freeway was realigned after the Y!WMS image was taken? Sure. I'd say any one of those three potential edits is worthy of removing reviewed:no. Just disconnecting the overpass from the freeway is a big topological win. Improving the curve of the exit ramp is only decorative from the point of view of topology, but important to us humans. (I saw a 270-degree ramp on I-5 that had three nodes. A "triangular ramp." Like Picasso decided to do freeway design for a week. [1] ) Likewise, splitting the carriageway is important to getting the map right. Must you do all three? If so shouldn't you have a gpx trace to back it up, or is aerial imagery good enough? So currently, I think removing the reviewed:no means, "I've improved this" rather than, "I've perfected this." To encourage or support more demanding requirements should surely be backed with a tool that reminds and suggests how to "fix" TIGER. Not just an anthropomorphized paperclip asking "Shouldn't your motorway have grade-separated interchanges?" Naw, nevermind. The paperclip is the way to go.
