I tried this manually in pbuilder/buster to understand what problem
britney encountered. I didn't see this in my piuparts tests.

# britney reported problems for libmariadbclient-dev
# and tried to migrate both src:mariadb-10.3 and src:mysql-defaults
apt-get install libmariadbclient-dev default-mysql-client-dev

sources.list += sid, apt-get update

apt-get install libmariadbclient-dev default-mysql-client-dev
# selects 1:10.3.12-1 where available
# boom - libmariadbclient-dev is no longer installable, so the migration
# would require immediate removal of mariadb-10.1 to succeed which would
# have more implications

# let's add -2 with the new transitional package
sources.list += /tmp/mariadb, apt-get update

apt-get install libmariadbclient-dev default-mysql-client-dev
# selects -2
# worked fine

While on a normal upgrade path libmariadbclient-dev might just get
removed, britney actually cares that the installability of the packages
in testing does not regress.
