It looks like openSUSE is providing both, MariaDB and MySQL, with MariaDB as a default[1].

And if someone is using upstream themselves they are responsible to
manage that ... and assuming the versioned obsoletes is used as
discussed yesterday then there would be no accidental overwrite and
compatibility if mysql-5.6 is on the system and the admin updated

Is it really hard maintain both? May be it have worth also package and
support Percona with XtraDB?

The question of maintaining both will be probably re-evaluate in the future again, there may be some new opinions for any way.

Speaking about XtraDB -- MariaDB includes this engine so feel free to test it.
