I think you'll be interested in:

partman-zfs (8) unstable; urgency=low

  * Redesign ZFS pool management (mostly based on partman-lvm).  New
features include:
    - Support for ZFS pools with multiple physical devices.
    - Support for multiple filesystems within a ZFS pool.
    - Support for legacy filesystems using ZFS volumes (ZVOL).
    - Arbitrary names for ZFS pools, filesystems and ZVOLs.

which has just been uploaded to unstable.

Please test!

I know about the write cache issue, but I'm not sure how can this fit
into partman's workflow.  AFAIK partman always wants a partition
label.  This might require changes to other parts of D-I.
