Raspberry Pi4 is already available with 8GB of memory. Now that we are way over the minimal memory requirements of ZFS, I think this topic should be reconsidered. Using zfs-dkms is a bit tedious, having the ZFS kernel modules available with the arm64 standard kernel would make the life much easier.

( Even zfs root can be enabled manually with arm64 eoan builds using a variant of the steps at https://github.com/zfsonlinux/zfs/wiki/Ubuntu-18.04-Root-on-ZFS . ) Currently one has to install zfs-dkms for zfs support, but ideally one would have zfs modules come with the standard arm64 kernel so that one does not have to recompile zfs on the pi. Example: uname -a Linux rpi4 5.3.0-1011-raspi2 #12-Ubuntu SMP Fri Nov 1 09:07:06 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux @rpi4:~$ zpool status pool: bpool state: ONLINE status: Some supported features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not support the features.
