I don't see why this would make the experience better. Java has been a huge part of Android's success allowing for backwards compatibility in a smooth manner. Java should also be given credit for Android's stability, due to its lack of memory safety errors. IMHO Google shouldn't pull-back from using Java (or Kotlin). Rust could be an option but that would certainly degrade Android's developer experience.
