The Center's mission: "Organize open source projects around Scala".
About scala-native, no details are given on whether it targets scalac or Dotty
(which another talk [2] describes as a couple years away from production-ready).
The situation could change if, say, Akka or Play announced a Roadmap for Dotty.
The question remains how well Scala 2.12 will help in migrating to JDK 8.
The Github activity of the scalac core contributors [1] [2] [3] shows no hurry on that.
