> In my view, the source key is crucial to every object. I don't add the source key to anything which I've done based on GPS traces/waypoints. I try and add it on objects I add from other sources though (NPE, OS Opendata, Bing for example), but as someone else has says, this won't always go in the source key - I've surveyed lots of houses and while the building outline might be sourced from StreetView or Bing, the house numbers, whether it is semi-detached, part of a terrace or whatever is based on survey, so I would use say source:building to indicate where the outline came from, but the other details are from survey.
So I don't see the source key as crucial. What might be an idea, if it isn't already done, is record what background is in use when the changes are saved by using a tag on the changeset rather than every object - this won't say whether the user has changed during the session (though I guess this could be tracked and used rather than just whatever is current, but more work).
