Whether to enable using zfsGetType if your zfs get supports a -t argument for filtering by dataset type at all AND lists properties for snapshots by default when recursing, so that there is too much data to process while searching for backup plans. If these two conditions apply to your system, the time needed for a --recursive search for backup plans can literally differ by hundreds of times (depending on the amount of snapshots in that dataset tree... and a decent backup plan will ensure you have a lot of those), so you would benefit from requesting this feature .
