For convenience we should provide a command to set the threshold, right now it's something like echo 1 > /sys/fs/btrfs/$uuid/qgroups/drop_subtree_threshold where the uuid must be found by other means.
Related note: we also have per-filesystem quota_override, an command may be also good, with unified naming. We have the property command so current suggestion is to set it like that instead of adding set/get command to quota or qgroup.
