With the most recent releases (2.0.1 & 1.0.3) it looks like branch 2.x is compatible with Drupal ^10 and branch 1.x is compatible with Drupal ^9.4.
The recommended steps for upgrading from Drupal 9 to Drupal 10 are to use the Upgrade Status module to track contrib module compatibility. Once all contrib modules have been upgraded to be compatible with Drupal 10, then Drupal core can be upgraded from 9 to 10.
Having 2.x only be compatible with Drupal 10 (and not ^9.4) breaks this process. I'd like to upgrade 1.x to 2.x as part of the process before having to upgrade to Drupal 10. But as it stands now, that's not possible.
I realize that since this module came from core it might track core so closely that 2.x just might not run properly on D9 and that's all there is to it. But if 2.x can technically run on D9 (or ^9.4 or ^9.5) then it should allow it in its .info.yml file.
No it's not compatible with Drupal 9 because of changes between symfony 4 and 6
