The 'exception document' is an interesting idea, and I'd like to
explore this concept further with some advice from the FSF. We don't
want to create an altered version of the GPL (obviously), but I
wonder if the exception document would make sense to include in
Drupal's default download, clarifying some things like the status of
theme template files, 'intermediate' integration modules, etc.
As noted by the FSF, however, it's difficult to open the door to
integration modules 'officially' without opening the door to closed-
source modules. It becomes easy for someone to simply build their
functionality as a closed source module, and wrap it in a
'compatibility layer' rather than engaging with the community and
participating in the sharing of code and resources that has made the
Drupal world thrive.
