Hmm... I wouldn't consider some writing illustrated with an image of mine to be a deriviative work of my image.
Would you consider a film with a music composition a derivative of the music? CC-BY-SA does. I'm not sure I would get hung up on the exact meanings of "derivative work"; I think it makes more sense to emphasize the _semantic relationship_ between two combined works.
If CC's "SA" were to acquire this meaning, we'd have to disallow it for all Wikimedia projects that are GFDL, wouldn't we?
Not necessarily. CC-BY-SA 3.0 will include a compatibility clause: http://creativecommons.org/weblog/entry/7234
If this will include the GFDL, a strong copyleft CC-BY-SA would allow a third party to either comply, or migrate to a compatible license.
We've always held that GFDL combined with other pictures and media are "mere aggregations", so it may be in our interest not to advocate a strict interpretation of existing licenses. But it doesn't seem at all unreasonable to me to desire stronger copyleft protection for works which are, in their nature, unlikely to be significantly modified directly.
