(Hi, Scala Tech Lead at Typesafe here.)
The Scala landscape is pretty far off from the node/io fork, I think. First of all, we are keen to keep Typelevel Scala and the official Scala distribution in synch. We're also seeing a healthy acceleration in contributions (proposed & merged) over at https://github.com/scala/scala#welcome -- all contributions welcome!
In any case, we're happy to see experimentation over at Typelevel. If you're interested in this kind of stuff, I'd recommend also taking a look at https://github.com/non/cats.
