The problem I can see with conflicting with mysql-server-8.0 is that a user could have both MySQL and MariaDB installed on the same server, as they should be able to co-exist (listen on different ports).
If we conflict, then we prevent that. The issue is that in Debian default-mysql-client and virtual-mysql-client (and -server) depend on mariadb, but in Ubuntu they depend on mysql. Perhaps we should explicitly depend on the mariadb packages. Thinking about this is a bit further, this does seem the best option. RT 5.0.4 supports MySQL 8, which is now in Debian Unstable, so this'd only apply to the RT4 packages now.
