A pure Clojure stack is extremely rare in most organizations. And integrating data from microservices with data lakes and observability platforms is not "SDKs of the month" but a normal business concern. What I am trying to say is that immutable state may be one aspect of something much larger that did not factor into Nubank's original decision to use Clojure for microservices. It may have clear benefits there (and in your case - I don't deny that), but downstream you pay for that rarity by having to build every integration yourself.
