Description

After upgrading one of our v8 installations running on PHP 7.0 to version 8.7.9 it started throwing exceptions about nullable return values (the question mark flag to allow null returns) in the Symfony yaml parser. The composer dependencies of symfony/yaml state "^7.1.3" for PHP - so the latest TYPO3 core update actually raised the minimum PHP version implicitly to 7.1, even though 7.0 is the official requirement.

This could bring a lot of installations down when they update.
