If you ship in Akonadi a facility that does the above and has some sorts of "API" to call, I can modify the MariaDB maintainer scripts to call it. Regardless if you do a technical fix for this or not, you could submit an addition to the release notes similar to what I did in https://salsa.debian.org/ddp-team/release-notes/-/merge_requests/197 and explain to Akonadi/KDE users, that before doing the Bookworm -> Trixie upgrade they should maybe log out all users and as a single root user session run the `apt upgrade`?
