I agree with your point, but I'm not sure how it ties in to the comment I was replying to. Edit: You seem to be overlooking the less tangible contributions languages like Rust or Haskell have made to PLs in general. One example that comes to mind is how Scala has affected the development of Java, even though, in the real world, Scala use is relatively non-existent.
