The feature in question matters. I don't see how you would fit async / the GIL in a beginner course. But if pattern matching is seen as idiomatic for basic code, then it should and will be introduced to beginners. For instance the switch / case construct is on https://learnxinyminutes.com/docs/java/ https://learnxinyminutes.com/docs/java/ (interestingly not on https://learnxinyminutes.com/docs/c++/ https://learnxinyminutes.com/docs/c++/ !), implying that it's quite basic there.
