Misleading Documentation on https://mariadb.com/kb/en/getting-started-with-mariadb-galera-cluster/

https://mariadb.com/kb/en/getting-started-with-mariadb-galera-cluster/
The documentation is misleading and outdated
1. mysqld --wsrep_cluster_address=gcomm://
gcomm:// is deprecated use --wsrep-new-cluster instead
2. "MariaDB Galera Cluster comes with the following following SST scripts:"
Reader have the assumption MariaDB Galera Cluster only ships with the mysqldump sst. Thats wrong. I.e. rsync and xtrabackup are also shipped.
The user just have to make sure to install rsync/innodbackupex to use them.
3. innodb_locks_unsafe_for_binlog=1 is outdated also
Think about what this would mean to a OLTP Installation
