That's what people would tend to think but you're forgetting about quite a few other heavinly beings up there. The show hasn't even touched on them because I figure few people even know or ever heard about them so they're sticking with what people know already.
Working off of the angelic hierarchy then the order from highest to lowest is...
The fact they probably only use Angels and Archangels in the show is because, iirc, those are the only two that can have direct contact with humans? I'd have to double check. The others are up in heaven making sure the universe keeps turning or w/e.
Ahh yeah... good recollection
I remember when Cass mentioned in S5 about cupids and other types of angels who "kept the wheels running", but even then he said they took their orders from Michael and other "executives". Add to that the fact that Anna said that the archangels are only angels who've seen God face-to-face... and the fact that archangels dont need to be "connected to heaven" to use all their powers. All this led me to believe they were highest 1337s of heaven.
But yeah, you're right about the show building its lore on what's popular with the people, so we probably wont be seeing all those other creatures.
