Maybe replacing containers...I had a better developer experience and a better overall quality of life when I deployed war files into a servelet container (tomcat). I wasn't patching operating system vulnerabilities across a jagged sea of micro service images or patching vendor supplied images either (literally had to do that with Kafka). I deployed a fucking war file. That's it. And I'd also imagine that a WASM module\app would have a much snappier start time without having to lug around the overhead of a container...And "Alpine Linux" can go ahead and kiss my ass (no offense).
