Which wiki describes that?

Apart from JOSM, which editors allow that?

Could you expand on 'tracking' please?
Individual entities can have multiple source tags added at different 
times. It would be far harder to 'track' their sources if only add to 
changesets. When editing an object you can instantaneously see the 
sources if added to it.

Not true, you can individualize the source tag with hyphens.
