Not quite, based on what Richard is saying. It would allow future
relicensing but only if the new licence remained compatible with the
terms seen to be required by the OS (currently attribution, if I've
understood correctly).

It's an unfortunate limitation, certainly, but not quite the same as
condemning us to ODbL or CC forever.
