Simplenetes does support state, no sweat. But it can't pull a disk out of the cloud for you, there is some traditional Ops involved.
However, if you are just dealing with a three node cluster (Yes I know many of you are running tri-cycles with k8s stickers on it) then maybe it can be fine for many applications to not have a scheduler.
Simplenetes does however support multiple replicas of pods so if one node fails it can be OK.
Why do I need 17k lines shellscript to run my tri-cycles? I would rather recommend using docker swarm or just podman itself.
you are adding more complexity without to a very simple problem.
