Not really, as the numbers show

What was crucial for Kotlin's adoption was Google's decision to 
push Kotlin ("my way or the highway") for anything new on Android 
frameworks, while stagnating Java support on purpose.

Those lucky ones with Android 12 devices might get an update for 
OpenJDK 11 LTS support, Java subset, but several of new Jetpack 
frameworks are only accessible via Kotlin.
