Few things comes to my mind:

Kotlin is JVM + Java interoperable language and this is its major if not sole selling point. So it does not help Google in any way regarding Oracle-Google copyright and patent issues.

Any kind of support might come when some developers get down and write lot of code to support that language. Android team is not going to add any support just because someone wanted or voted to support new language on Android platform.

At least people who wanted Go on android have written extensive amount of code to add support and still they are far from done.
