Ineed, one needs explicit permission from the FSF to change the
license on any text that is copyright FSF.
I'm sorry. I thought that the people here were able to give that permission. I will not make any changes until I get a formal notice on the subject.
If you, and/or the FSF, are not comfortable with a general exception, a specific exception for that example backend would a potential alternative.
Thank you for your time. (also, your contributions to culture, and for Emacs.)
