Hello! Seems upstream devs are working on https://jira.mariadb.org/browse/MDEV-25672 Once 10.5.11 is available we will work to quickly introduce it to Debian.
You can get the previous version in Debian (10.5.9) and deploy that on your systems if you want. We don't plan to do any Debian-wide special tricks for this one, we will just wait until there is a new upstream release.
