So far this looks good, I see no more cases of default-mysql-server 
being held at the buster version (and thus mariadb-server-10.3 instead 
of mariadb-server-10.5 being installed).

you can find a 990708 branch in both repositories

I don't think anything needs to be fixed in stable.

Some general understanding question: Would mariadb-server-10.5 work with 
galera-3, too? (with only the Depends being relaxed to 'Depends: 
galera-4 | galera-3, ...', without recompilation or similar actions)
(Bonus question: would mariadb-server-10.3/buster work with 
galera-4/bullseye with only the dependencies similarily relaxed?)
That could allow for even easier solutions.
