I'd like to know if anyone can give any inducation on when Symfony 7 will officially supported?

We're having an issue, having tied to upgrade to Symfony 7, because api-platform/schema-generator is conflicting with sebastian/comparator, which is required by newer versions of PHPUnit, so we cannot perform the upgrade.

There is an issue open on the schema generator repo, but it has been open for nearly a year without any activity at all.
