Whoops! Looks like I've blundered. Or, as a politician might say, a mistake has been made. I have fixed it now. Sorry, TRex, and anyone else affected.
Even if I had made the word rare when I said I was going to, it wouldn't have appeared on the Word List Suggestions page, because that list shows changes of common/rare status only since the start of 2013. I hadn't kept such careful records of those changes as I had of new words being accepted, so I decided it would be more trouble than it was worth to try to put all the historical common/rare changes onto the page.
