Yeah. Rollbacks or reruns are hard when dealing with external systems. Actions need to be idempotent for reruns to work.

One thing you may focus on is making workflows more durable: Checkpointing and sending to users summaries of last checkpoints when things fail.

The last thing you want a non-tech user (your target customer) is to figure out what’s the state of a failed workflow.

Great idea -- we're looking at showing workflow history and this is a good addition.
