$appRootDir is not used, you could remove the assignment.

        // The "framework.templating" option is deprecated. Please replace it with "framework.view"
        $config = $this->processConfiguration($config);

It seems like $config can also be of type object; however, PPI\Framework\ServiceManager\Config\TemplatingConfig::processConfiguration() does only seem to accept array, maybe add an additional type check?
