They are enabled in order to facilitate the "Cleanup based on Disk Usage" feature in snapper - http://snapper.io/2016/05/18/space-aware-cleanup.html
Considering "snapper made too many snapshots and filled up my hard disk" is by far the #1 complaint from openSUSE users from the last few years, I would say that the features required to mitigate or remove this problem are most certainly required to be on by default on a user system.
and that would be good but TW default SPACE_LIMIT is set at 50%! over-the-top suse defaults have created and urban legend around the excesses of snapper. and all to achieve what in the typical use case? this is funny [http://www.linux-magazine.com/Issues/2015/176/Snapper] "If you leave the default settings in the /etc/snapper/configs/root file, the snapshots will quickly consume a huge amount of space. A root partition, which can normally make do with 30GB, will need between 100 and 300GB of disk space for snapshots" -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
