Great example. I worry about adding a layer of abstraction over provisioning resources this way.

Of course we have to try this because it's a badass (tho obvious in hindsight) idea, but in practice it might have some downsides.

Does the create during this time window return a specific enough error? This seems like the exact case where a controller that never gives up could provide value. Though I'm kind of amazed this is on the order of an hour instead of minutes.

This issue already exists with, say, Terraform to orchestrate infra with code. The solution is to append a random hex string to the resource unique identifier.

This AWS project will need to support a feature like that.
