You know quite well that the removal of this restriction is brand new and it would be very easy to encounter it in the wild.
Why do you go out of your way to use smarmy tactics to argue against anytime someone who has a legitimate complaint? It would be way more productive to acknowledge the weaknesses and then tell the good story of Scala.

Are you claiming that there wasn't an arity limit on case classes that you could run into through no fault of your own using the Scala web stack? Or just that if you had to diagnose that problem it shouldn't bother you as it isn't a valid complaint?
What would elevate someone from HN "armchair expert" in your mind, such that their complaints were valid? Is it even possible for someone to mention something they don't like about Scala without you immediately dismissing them as not knowing what they are talking about?
