I'm not convinced one "cannot" do it with an existing programming language, as the link states.

I agree that the ergonomics of a languaged planned for that is better. But the argument that it's *only* possible with a purposeful language doesn't hold, in my opinion.

Afaik, the AWS CDK allows to express both preflight and inflight in JS, Python, and others, and it works well. Again, the CDK gives an arguably worse experience, but not "impossible"...
