There exist cases where people are *now* using OSM under CC-By-SA,
with full respect of all of our community guidelines, where they will
have to stop using it if OSM becomes ODbL-only.  This is because share
alike licenses are incompatible with each other, even though as some
human-readable summary says the two licenses are similar in spirit.
