Yes, those are good points.
So if users can just install xtrabackup stand-alone like from a Percona
package, that might actually be better than including it in MariaDB.
Once we get into distros, it will in any case be seamless, users will just
eg. apt-get install xtrabackup, and it will not matter from where it comes.
(and we could depends: or recommends: it from the mariadb-server package).
