> What is snapper cleanup is called after every install/upgrade action,

As a default, this seems a bit too heavy to me, but as an option it sounds
useful, indeed. We actually have the framework already, cf.:
        /usr/lib/zypp/plugins/commit/btrfs-defrag-plugin.py
(package "btrfsmaintainance").

Free-space-based decisions are being worked on; it needs btrfs subvolume
quotas and snapper working together.

This is already there in SUSE Linux Enterprise 12 and also
openSUSE 13.2 (screenshot attached).
