The same reason I don't like AWS' Step Functions. The spec in JSON is horrible. On the other hand, Step Functions is pretty scalable and reliable and can take practically unlimited throughput.

Now that Step Functions has gained momentum, they can construct higher-level APIs and SDKs to translate user spec to the low-level JSON/YAML payload.
