The [project:clear-controllers|INFO] task clears all non production environment
controllers:

  [./symfony project:clear-controllers|INFO]

You can use this task on a production server to remove all front
controller scripts except the production ones.

If you have two applications named [frontend|COMMENT] and [backend|COMMENT],
you have four default controller scripts in [web/|COMMENT]:

  [index.php
  frontend_dev.php
  backend.php
  backend_dev.php|INFO]

After executing the [project:clear-controllers|COMMENT] task, two front
controller scripts are left in [web/|COMMENT]:

  [index.php
  backend.php|INFO]

Those two controllers are safe because debug mode and the web debug
toolbar are disabled.
