Yes but one subtle point. Exactly once processing is not possible in these frameworks, they assume execution is idempotent which means at least once.

Now, any system I’ve seen designed around exactly once is complete garbage.

Not entirely true, DBOS can guarantee exactly once execution if your API calls are idempotent.
