Symfony 4 is much more lightweight than previous versions. If you create a new symfony 4 project with composer you just get an empty project with just a hand full of dependencies. First time I tried out the v4 (coming from 2.x & 3.x) I thought that the installation did not work properly because stuff like twig (for templating) and other things were missing. The whole integration in composer with the symfony flex component makes developing even easier than before: https://symfony.com/doc/current/setup/flex.html https://symfony.com/doc/current/setup/flex.html
