I don't know what is the policy for major versions, but this code is only supported since 9.4, although I haven't put this dependency for the moment.

I'm also not clear what the code does, I just changed the if the getImplementations for the hasImplementatiosn and the code that saved the logs a warning of the deprecated code, but that can no longer be used in Drupal 10.
