Regarding the Recent changes in Prefect Orion, Blocks - Is blocks needed if our ecosystem is Kubernetes + ConfigMap for Non-secure values and Kubernetes + Vault/Opaque secrets for Secure values ?

No you shouldn’t need Blocks, but you may find them more convenient too

Sure, but our Ops has wired everything with Vault enabled Helm Chart and Kube Operators and its auto-refreshing AWS secrets capability

Yeah if you already have a setup, there’s no need to go to Blocks
