Actually I do see this warning in e.g. https://salsa.debian.org/mariadb-team/mariadb-server/-/jobs/8130323 and https://salsa.debian.org/mariadb-team/mariadb-server/-/jobs/8130324
However, it is not preventing the service from starting nor does it emit an exit code.

Fixed in https://salsa.debian.org/mariadb-team/mariadb-server/-/commit/48ef3c2dcd2fde4e747852f5c3fda1fcc18f0e11 I will proceed to upload this to bookworm-proposed-updates now.
