I have Magento 2 with sample data and I came across this file


The Interceptor file is generated only if any module wants to plugin (before/after/around) any method in given class . for example, this method renderResult() does not have any plugin like beforeRenderResult/aroundRenderResult . then Why interceptor file was generated ? Are there any other scenarios where interception file can be generated ?

public function renderResult(\Magento\Framework\App\ResponseInterface $response)
    $pluginInfo = $this->pluginList->getNext($this->subjectType, 'renderResult');
    if (!$pluginInfo) {
        return parent::renderResult($response);
    } else {
        return $this->___callPlugins('renderResult', func_get_args(), $pluginInfo);

Plugins are inherited. Magento\Framework\View\Result\Layout implements Magento\Framework\Controller\ResultInterface and this interface have plugins

<type name="Magento\Framework\Controller\ResultInterface">
    <plugin name="result-builtin-cache" type="Magento\PageCache\Model\Controller\Result\BuiltinPlugin"/>
    <plugin name="result-varnish-cache" type="Magento\PageCache\Model\Controller\Result\VarnishPlugin"/>
