Idempotency and safety is about how to send POST requests, rather than how to handle them.

You can't pre-fetch a POST request, or re-try after a timeout. Because you have to consider that the POST request could have unintended consequences if sent too many times.

That looks more of a documentation problem, rather than an HTTP problem.

You just document that that POST endpoint doesn't actually modify data.

A great example of this are OpenAI completions.
