Cool, so I can start a new service and bind activities to it from Rust without having to deal with a nasty JNI or an unstable ABI that changes under my feet?
That's hardly the full story. Rust provides all the support it is able to provide for Android, yes. But it still relies on the NDK and has to sit behind a JNI layer. A "Kotlin vs Rust" comparison for Android is apples and oranges.
What do you mean by "first class support" here? Some quick searches doesn't give me results that goes in this sense (nothing official from the rust and/or android projects).
