Every commit in MariaDB in Debian runs extensive CI on Salsa-CI and I
can assure we make sure not to break anything on new uploads.

However, MySQL 8.0 is not in Debian and does not test anything about
compatibility, as the Oracle employee stated in the Launchpad report
explicitly. So their upgrades will break stuff unless they change
their stanze and start testing for MariaDB compatibility (which is
essentially just the same as testing for compatibility with earlier
releases, such as MySQL 5.7 or 8.0).
