Thanks for putting in all this work. People should get more credit for writing good survey articles like yours.
One of the regrettable quirks of our industry is the way we replicate theoretically language-neutral components separately in multiple language ecosystems and verticals. I wish we didn't a separate npm and cargo. I wish the polyglot runtimes you mention (especially Graal) would see more adoption. I wish we didn't have both Duktape and MicroPython. There's nothing language-specific about efficient garbage collection or compact bytecode or package dependency resolution.
