That's right wrt Debian. Now that's a real
shame that
GFDL has such options at all - they're all plain non-free.
Similarly, the Open Document License has free options A and B.
Enabling them renders the licence non-free;
the fact that they may be enabled later renders it non-copyleft.
The Creative Commons SA licence, in contrast, has no such problems.
It is by any objective measure the superior licence;
however, we really should license Wikibooks disjunctively with the GNU FDL,
so that books can borrow the substantial material from Wikipedia if useful.
