Given a migration back to MySQL is not out of the table for us WMF DBAs,
and I will complain if we drop compatibility; I would say both MariaDB and
MySQL will probably be supported for as long as the databases are or even
more- we just "upgraded" the requirements from 5.0 to 5.5 for newer mw
versions.

That is annoying, and even more worrying to me is MariaDB roadmap about
free software/lock-in: https://mariadb.com/bsl-faq-mariadb

If you are in charge of a mediawiki installation and want to know the
ops/db maintenance side of things, get in contact with me on phabricator; I
would be glad to share experiences.
