Thanks a lot for the revert. Just a small note: changing the tests while doing the revert made it extra difficult to apply this revert to earlier revisions. I'd rather we do clean reverts (which also needed a conflict resolution in this case) then do other modifications separately maybe. Not sure if it would have worked here, but it would have been things much less complicated I guess.
