symfony: max[self]=0 in PHPUnitBridge also fails on external deprecated services

Symfony version(s) affected: 4.3.5, probably more

Description

I’ve been trying to use the PHPUnit Bridge to avoid using code, that we have deprecated on our own. So only my own deprecated classes should make the tests fail, but not if I am using a deprecated Symfony class. As far as I understand I would say that this is describes as internal deprecations in the docs.

However, when I am executing the tests, I also receive a message like this in the “Remeinaing self deprecations section”:

The "templating.locator" service is deprecated since Symfony 4.3 and will be removed in 5.0.

I guess that is not the way it is supposed to work? 🤔

How to reproduce

I am using a config like this:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit bootstrap="./vendor/autoload.php" colors="true">
    <testsuites>
        <testsuite name="components">
            <directory suffix="Test.php">./src/Sulu/Component/*/Tests</directory>
        </testsuite>
    </testsuites>

    <!-- Code coverage filter -->
    <filter>
        <whitelist>
            <directory>./src/Sulu/Component/</directory>
            <exclude>
                <directory>./tests</directory>
                <directory>./vendor</directory>
                <directory>./*/Tests</directory>
            </exclude>
        </whitelist>
    </filter>

    <php>
        <env name="SYMFONY_PHPUNIT_VERSION" value="8.0"/>
        <env name="APP_ENV" value="test"/>
        <env name="SYMFONY_DEPRECATIONS_HELPER" value="max[self]=0"/>
    </php>
</phpunit>
