This is an interesting idea, but why don't they just use the outside service as a queue, because it works as one, and when it doesn't, this complete direction doesn't work either. easier when doing eg serverless because it’s hard to keep that long lived connection for indefinite amounts of time versus simply exposing a stateless HTTP API You mean "functions" or a similar thing? It may be the reason I think. I didn't know that serverless discourages using idle persistent connections.
