Of course, but we won't distribute it in main in any case.

That requirement is explicitly stated in DFSG3:

We don't require the right to relicense. That isn't a restriction on
what kinds of derivations you can make, only a restriction on how they
may be licensed.

The DFSG explicitly requires the legal right to make derived works, even
if making such works is not a good idea for technical reasons. "I think
it would be better to copy the ideas and not the content" is a technical
issue, but "it should still be possible to copy the content" is a legal

Of course, which is why you would want to modify that documentation.

Again, the DFSG does not require the right to relicense modifications,
only to make them and distribute them under the same license as the

That is why the Social Contract forms the basis for interpreting the
Guidelines when we run into a gray area that the DFSG does not
explicitly cover (such as "you must send all modifications to the
author"). However, the right to make modifications and distribute them
under the same license is not a gray area, since it is explicitly
covered in the DFSG.
