http://wiki.openstreetmap.org/wiki/Quick_History_Service has an override table. You can put someone in this table that has not accepted the CT. That override now makes the service pointless. It makes the tools in JOSM and Potlatch pointless too. If you don't redraw some issue that has been overridden, then you just might not see that part of the map when it is re-licensed some day. If someone doesn't want their edits flagged, then accept the CT and say that your contributions belong to the public domain.
