Package: partman-xfs Version: 68 Tags: patchXFS supports the "discard" mount option but partman-xfs does not offer it. Even though fstrim is the preferred discard method, partman offers the "discard" option for other filesystems which support it such as FAT, ext4 or Btrfs so it should also support it for XFS for consistency.
