MariaDB Galera Cluster and MaxScale support

We are planning to increase our number of licenses
but your support team informed us that MariaDB Galera Cluster and MaxScale are not officially supported.
We are a bit surprised about this because MaxScale is a transparent Proxy/LoadBalancer and Galera will not affect SQL statements.
Of course, adjustments are necessary, but the two products are rising enterprise products.
In the future we will migrate a large part of our databases to MariaDB Galera Cluster and we are looking for a suitable Database Management Software.

Please support MariaDB Galera Cluster and MaxScale.
I am looking forward to hearing from you.
