I'm not going to waste my time updating a source tag on every node,  
way or relation that I touch. However I'm happy to add ti to the  
changeset where it belongs.

The tools can be improved to look up the tags of all the changesets in  
the history of a particular object. I think that this will give better  
information as to the sources of the edits over time.
