I think this shows one of the benefits of adding source tags to our edits - because in the future a better source may come along.
At the time a lot of natural features in the UK were traced from NPE maps and they made many parts of the UK in OSM much better than nothing. It's really encouraging, and we should further encourage folks to re-map and edit areas. When I encounter something tagged with NPE as the source, I feel more confident moving and editing it whether aligning a stream to Bing imagery or to my GPS trace.... we'd also need to remind people to change the source tag as well! Cheers and happy mapping!
