> I would bet good money that most of the management in charge of the websites that make up the web would not waste dev time on migrating to some minified JS file replacement, when webpack-style minifying works "just fine" and allows your team or whatever to keep churning out new features

I don't think so personally. Code size is a huge issue for page performance, and a "bytecode" format would probably be 2-3X smaller and 2-3X faster to parse. Together, this might triple JS loading speed. Maybe double the loading speed of JS heavy sites.

JS with sourcemaps isn't so different from compiled code with debug symbols. The sourcemap support could probably be adapted with minimal work. And its likely the transition would be transparent to most users, nobody really looks at the minified JS as it is.

Another big advantage is vastly simplifying JS parsing and JIT compilation. In Java and C#, most features are added without changing the code format. And when it does get updated changes tend to be minimal. Upgrading browsers and minifiers every time JS adds a language feature is a real burden on the ecosystem

I'm not talking about convincing devs, I'm talking about convincing management that big bang refactor that hypothetically results in better performance numbers is worth the opportunity costs on new features you couldn't deliver. Or the opportunity costs of saving that money spent on devs.

The worst parts of the web do not prioritize latency numbers, so I don't see how you'd convince them that it's worth it, and any backwards-incompatible changes to the web (to force them to make the change) have historically had poor uptake from consumers, devs, and browsers alike.
