// itself. Applying the Kotlin plugin on top of it fails configuration with
// "Cannot add extension with name 'kotlin'". Asking for the extension covers
// every way built-in Kotlin can be turned on -- the global default, the
// android.builtInKotlin property, and the per-module com.android.built-in-kotlin
// plugin -- without reading an AGP version number.
