GFDL licensed images are still perfectly usable in freely licensed reference works, in spite of the inconveniences in the license.
I am not sure what you mean, exactly. Do you consider GFDL to be “strong copyleft”, i.e. that the viral clause applies to the text surrounding a GFDL image? In that case, I don’t see where the “freely licensed reference works” come from (GFDL does not talk about “freely licensed”, only “under precisely this License”), and in that case, CC-BY-SA-only Wikipedia articles would not be allowed to use GFDL-only images. (In a similar way, GFDL-only Wikipedia articles of a recent past would probably not have been allowed to use CC-only licensed images.)
