You are right about requiring more case studies. In the same context, MV3 extensions are being moved away from persistent background pages to ephemeral service workers. There's a thread and several very popular crbugs for how the web-based service workers don't work well for extensions (https://github.com/w3c/webextensions/issues/72). Given all this, the Chrome team continues with the change citing increased performance when using service workers. However, even when extension developers continue to come out with claims of decreasing performance, the Chrome team - as in the malware case - has not provided any case studies on how it is so sure about the increased performance (or efficiency, memory use, etc.) of SWs.
