I'm not sure that I agree with this being set to "Needs review". The last
progress that I see made on this was me hacking at the patch to remove some
equivalence class limitations. I think the logical next step would be for
you to look at these changes and either accept or reject them. So does that
not suit "Waiting on author" better than "Needs review" ?
