Copilot's comment makes sense to me.

This is the extension function imported:

fun <T : Any> NamedDomainObjectContainer<T>.id(id: String, action: (T.() -> Unit)? = null) {
    action?.let { create(id, it) } ?: create(id)
}

We use it here:

private fun GenerateProtoTask.addProtocPlugin() {
    plugins.apply {
        id(PROTOC_PLUGIN_NAME) {  // <----- HERE
            val path = project.codeGeneratorRequestFile
            val encoded = path.base64Encoded()
            option(encoded)
        }
    }
}
