Is ODbL licensed content compatible with the current CTs?

My understanding is that ODbL does not allow you to grant "a
worldwide, royalty-free, non-exclusive, perpetual, irrevocable licence
bla bla bla..." to anyone.  So no ODbL licensed datasets can be
contributed to OSM.  None at all.  And that includes ODbL content that
came from OSM in the first place.
