Surely there is a lot of workload is delay-able, but there is equal, if not more, amount of workload that do not have the luxury of waiting. Is it fair to say the serverless platform has no advantage for the latter workload?

perhaps they should have called it serverless batch, or Batch-as-a-service, async-serverless or serverless-futures.
