I've submitted a tested MR at:
  https://salsa.debian.org/installer-team/partman-btrfs/merge_requests/1

I decided to leave configuring @home up to the user, because the user
may wish to mount /home using another block device, possibly on a
non-btrfs volume.

Also, adding full-fledged btrfs subvolume configuration (eg: forking
partman-lvm) to DI will require a comaintainer.  The bus-factor is too
high for me to do it alone.

Would you like to take care of rescue-mode or shall I?


Cheers,
Nicholas
