I would imagine there are quite a few people who couldn't legitimately agree to that, even if they want the ODbL. Have you ever important any CC-BY(-SA) data using your account? If so, they I would think that you can't legally agree because you are not the copyright holder of all your contributions.

As I'm not the copyright holder of those base datasets, I don't see how I could agree to the relicensing, or contributor terms which allow for future relicensing.  Does that mean everything I've ever contributed (even my own work) has to be deleted? Probably.

Even worse, how do you know if stuff you've entered to OSM which is 
based on your own *and* other OSM mappers (CC-by-SA) work doesn't count 
as a derivative work?

Potentially, you would relicense stuff to the ODBL derived from existing 
CC-by-SA OSM data - which would be an illegal copyright infringement.
