I can argue this is not the case.
What 2.0 and 2.5 said was that "derivative work could be
licensed under 3.0, and 3.0 may include further ways to
switching to different licenses through creating a
derivative."
Creating a derivative of 2.0'd Work and releasing it
under FDL is not something 2.0 permits to a licensee.
Creating a derivative of 2.0'd Work and releasing it
under yet-to-be-published 3.0 is something 2.0 permits
to a licensee.
Creating a derivative of that particular 3.0'd derivative
and releasing it under whichever license that is okayed
in 3.0, is something 2.0 permits to a licensee.
