Comment 12 for bug 1576353

See the comment on the linked debian-cd MP from Marc Deslauriers. Note that the goal of removing the cloud-image seed is still entirely reasonable and doable, openssh-server should just move to livecd-rootfs as something always added to cloud images. Done and done. There's no reason that one package needs to be represented in a seed/task any more than custom kernels or cloud agents are.
