ZFS doesn't have thick allocations, every allocation is thin-provisioned, so resize operation is essentially a zvol size limit change (`zfs set volsize=X pool/zvol_name`).
Shrink is allowed too (which leads to data destruction), but shrink restriction is already implemented in libvirt, so this function doesn't need to check anything.
This patch is posted via PR too and has green test runs https://gitlab.com/libvirt/libvirt/-/merge_requests/495
