+/**
+ * This class is not needed anymore;
+ *
+ * ### Previous Usage:
+ * Previously the Kotlin Gradle Plugin used to distinguish between two kinds of 'plugins'
+ * The 'wrapper' (see 'KotlinMultiplatformPluginWrapper') and the plugin.
+ *
+ * The Wrappers were the plugins that were actually applied to the project when users requested Kotlin:
+ * ```kotlin
+ * plugins {
+ *     kotlin("multiplatform")
+ * }
+ * ```
+ *
+ * The code above would have applied the 'KotlinMultiplatformPluginWrapper'.
+ * Those 'wrapper plugins' then did run the 'main configuration code' and at some point created this 'wrapped' plugins manually
+ * and called the [apply] function.
+ *
+ * Its quite unfortunate that both entities implemented [Plugin] of [Project] and therefore the differentiation was not clear.
+ *
+ * ### Replaced by: Kotlin Gradle Plugin Extension Points:
+ *  See [registerKotlinPluginExtensions]:
+ *  Kotlin Multiplatform will register corresponding extension points to customise its behavior.
+ *  At the time of writing this comment: We take heavy usage of the [KotlinProjectSetupAction.extensionPoint] to provide
+ *  additional project configuration for multiplatform.
