Your project should contain a robots.txt file

More information: https://insight.symfony.com/what-we-analyse/web.missing_robots_txt

in public
The web root doesn't contain a robots.txt file. Search engines will ask for it, so not providing it will affect Search Engine ranking, and add load to the server needlessly.

Your project should not contain PHP files defining multiple classes

More information: https://insight.symfony.com/what-we-analyse/php.file_contains_more_than_one_class

in config/reference.php
This file contains 2 classes. Keeping only one class per file is a standard in the PHP community, since it promotes interoperability and maintainability.
