I have been explaining to folks how OpenAPI is basically WSDL-lite. And is building up to be as big, at their current velocity. Kubernetes and friends, it is hard not to see as non JVM Glassfish servers. I remember WAR files being far easier to reason about than the current bundle setups we have today. SAR files were an amusing stab at the same thing, complete with the server managing deployment/startup order.

I still don't want to go back to that time, mind you. Is probably why I'm so hesitant on the current attempts.
