Description
After running any command in dev (debug=1) I get a lot of messages in stdout like:

2020-02-03T16:37:57+01:00 [info] User Deprecated: The "Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand" class is deprecated since Symfony 4.2, use "Symfony\Component\Console\Command\Command" with dependency injection instead.

Console screen gets a bit messy.

That's very helpful but I don't need it every time I run a console command.
Right now the only workaround is to disable debug,because the error_reporting setting is ignored.

Previously (4.2) I just used an option in framework.yaml:

framework:    php_errors:        log: 4096

It was enough to get rid of those deprecations.
