We need statelessness for service reliability more than we need it for scale. There are a number of services that people use within our infrastructure that need to continue working even when a centralized DB is unavailable.
Logs are a good example. We expose logs as a NATS service, people auth and subscribe to their logs. It's useful to terminate auth right there both because it's faster and because it continues to work when the internet burps.
