[OSM-legal-talk] instead of replacing data can I just revert to the last known "clean" version?

I guess "ct=clean" would be better since there may be data which is usable
under the CTs but is not yet distributable under ODbL+DbCL.  (Recall that the
CTs require the content must be distributable under the current licence, which
means CC-BY-SA - this was clarified a few months ago by the LWG I believe.  Of
course in the majority of cases CT-able data is also ODbL-able.)
