Does Collections extension meet required licensing requirements?

I'm aware of two other licence problems:

Try making a book out of en:Taz people, or simply generate a PDF of the article. It seems that the extension tries to remove bots from the list of contributors, probably since their participation is below the threshold of originality so that they don't need attribution. The extension seems to try to exclude bots by searching for user names containing the word "bot", but note that the article has major contributions by en:User:Abbott, a normal user. Since the word "bot" appears in the middle of this user's user name, he isn't credited, clearly against the licence's attribution requirements. I tried to point this out at m:Book tool/Feedback#Bug: User with major contributions not credited but I'm not sure if this is the right place. Maybe it should go to bugzilla: instead?
No verbatim copy of the GNU Free Document Licence is included on English Wikipedia (but it seems to be included on German Wikipedia). GFDL doesn't allow any URL – you must include the full licence.
