If I collect a GPS trace of a road that is tagged as say 'source=NPE', I will adjust the road to match the trace, and change it to source=survey. That means that unless you look through the history there will be no evidence that it was once derived from another source...but, once you have surveyed it, I don't think it is derived from the other source any more, so this is fair enough?
