Comment # 57 on bug 1165780 from asf

Thanks Karl. 
But what i'm trying to say, is they are all useless for general audience. So
should not be forced on it. 
Im pretty sure there are many people not technical enough, to figure out why
their desktop became unresponsive once a week or once a month. Coz of
something, which is outdated and gives no benefits at all still intensively
work in the background. Defaults should be sane and tied for general usecase.
And btw there is already fstrim timer in suse systemd enabled by default. So
even the last one is useless. 

Those who maintain servers and happened to have redundant raid, can easily
enable scrub themselves in just a line of cron. Just like i did.
And scrub is the only thing which could be potentially useful in some cases
nowadays, out of the whole btrfsmaintenance package.

In other words: the package is long outdated Karl!
