You won't find it in a lower style of literature, and I think much newer (properly new, not 60s new) literature also avoids it. And if you use it in speaking you are downright weird (hence why newer literature, seeking a closer relation to spoken language, possibly a more natural feel, is using it less).

Legolas is also right that it is not emphasised in schools, certainly in Norway. It was mentioned a couple of times, but teaching us to use it was never a priority, precisely because we were unlikely to try to write a high literary piece in French, and because those of us who read that sort of French literature would be able to work out what was going on on our own.
