Is CUPS subscriptions.conf ignored in macOS 27?

Hi all, we're using a CUPS notifier in a custom printer billing software. In the current macOS 27 beta, the notifier is never executed although it's correctly registered in subscriptions.conf. Is this a bug in macOS or was the functionality intentionally removed? Thanks and greetings, Andreas
