The GFDL license states:
B. List on the Title Page, as authors, one or more persons or entities
responsible for authorship of the modifications in the Modified
Version, together with at least five of the principal authors of the
Document (all of its principal authors, if it has fewer than five),
unless they release you from this requirement.
Now, you see - in the current database dumps, which are used on most
of the Wikipedia mirrors (both online and offline), there's only the
very last contributor.
Wouldn't it be wiser to add the authors of the article, even if their
revisions should stay empty?
