@lirazel well, I wouldn't consider the main ship of even the tiniest yuletide-sized fandoms a rarepair, personally! like, say, Uriel/Little Ash is an obvious major ship from When the Angels Left the Old Country, so it still isn't a rarepair even though there are only 10 works for it on ao3, and I'm confident some of the ships I've tagged rarepair for cql have more fics than that!
