If Debian concluded that "GFDL-licensed works without unmodifiable sections are free", then the GFDL would be OK only if we make sure there are no "unmodifiable sections".
I'm not sure how much effort it would be to do that. Given that we've already released the User's and Developer's guide under GPLv2-or-later, we might as well use GPLv2-or-later for the man pages, saving ourselves that effort (and the effort of finding out how much effort it would be...), however much that effort might be.
