    > A requestId makes a submission exactly-once, so a client that retries after a crash gets the original submission back instead of asking twice.

    Sounds like a bug under a false assumption. Just having an ID cannot alone guarantee exactly once semantics AFAIK.

      The requestId is an imdempotency key, which is exactly how you get exactly once semantics.
