I doubt that it can.  This is one additional reason to continue offering the old
licence as a dual-licence option.  Those users of the map who are a bit legally
paranoid and want to be certain that no contributor can complain, can continue
to use CC-BY-SA.  (There is of course the problem of plagiarized data, as now.)
Those who are a bit more adventurous and don't mind the grey areas relating to
object history and what derives from what, can make use of the new things the
ODbL provides, such as the ability to make map tiles and distribute them under
whatever licence you want without having to give attribution.
