Thank you for explaining this. I understand your concern, and I appreciate the historical context. My intention with the proposed enums in https://github.com/php/php-src/pull/24111 was only to modernize the API and make filter usage more explicit, rather than to further weaken the extension’s original purpose. I’ll take a closer look at the history and rationale behind the removal of the defaults before proceeding. If the deprecation should be reconsidered as part of refreshing the filter extension, I agree that this is worth discussing first.
