[MariaDB developers] Commit ff4209fa0d1c66952bc9f00587f525314464e7be not merged on main?

Hi! I was updating the patch https://salsa.debian.org/mariadb-team/mariadb-server/-/blob/debian/latest/de... in Debian when importing MariaDB 11.4.6, and I noticed that the upstream commit that changes the same lines in https://github.com/MariaDB/server/commit/ff4209fa0d1c66952bc9f00587f52531446... only landed on MariaDB '10.11' and '11.4' branch, but never on 'main' or '11.8'. Could it be that 'main' has had zero merges from older branches since April 3? Or was there maybe some mistake and one merge was overlooked and it wasn't properly applied on all newer maintained branches?
