Changeset info can be obtained only from native OSM services. If someone
downloads shapefiles from Geofabrik or Cloudmade or OSM data in GML format
from my WFS server the changeset tags are a bit difficult to obtain. If 
such data contain osm_ids then it is possible to find the history of 
the objects from OSM services but I do not think it is compulsory to 
include osm_ids in WFS services or derived ODbL databases.

Users can delete or edit the object source tags but perhaps there are still
better possibilities that they remain in ODbL chain than the changeset 
source tags.
