Another question: If the toolserver had the ability to confirm that a specific user is an admin or a checkuser, would it be okay with German WIkimedia if tools would provide all information to admins or checkusers? (eg. even when other users haven't opted-in yet?)
In some cases, I would say yes. But it has to be decided on a case by case basis, IMHO. Saying "admins can see anything" wouldn't do.
I don't think it's consistent to say that german toolserver developers can run queries that admins can't, when some of us aren't admins, and most of us aren't checkusers.
Do toolserver developers need to start being careful about the private queries they run? Even though most of the data is available from download.wikimedia.org? (I guess the archive table is only partially available to people who have downloaded previous versions of download.wikimedia.org data)
