 * This class has the [Incubating]-level compatibility guarantees but is not annotated as such to avoid Unstable API warnings caused by the IDE
 * using this class as the Kotlin DSL script template. When the IDE chooses to use this script template, there is no direct usage of an incubating
 * API by the build author, but usages of the members are still reported as unstable API usages.
