The "remove from code review queue" is not that hard really, you can
just remove yourself (and reviewers you added) from reviewers. The most
helpful reviewers also comment on why they've removed themselves. If
reviewers removed themselves from patches they have no intention
whatsoever to review (which is fine), things would be much easier.
Other effective ways to effectively remove an open patch from the review
workflows (and from the korma stats, though not from [[Gerrit/Reports]])
is to self-give a -1 and/or slap a "[WIP]" in the first line.
