IMHO mappers licensing their data to the OSMF under CC-by-SA is not a 
useful concept, nor was it ever.  And if it is just because the license 
simply can't apply to the majority of contributions.

But I digress. Since in the arrangement between the mappers and the OSMF 
specific versions of the licenses are listed, it is clear that these 
cannot be changed without a vote. BTW a very good thing.

In any case as I pointed out before, the upgrade clauses allow 
recipients of the data to use a higher version of the license when 
-they- distribute the licensed object, they cannot affect the internal 
arrangements between the mappers and the OSMF.

It's two licenses, not three. The way I read it, parallel dual licensing 
would be possible.

But again IANAL.
