You have to realize that it is not at all in the interest of most commercial web applications to be transparently delivered as ES modules, all neatly split up and perhaps lightly minified. No, the fact that your 1000+ constantly version churning NPM dependencies and your proprietary business code are all bundled up in a big undecipherable blob is seen as a feature. The only thing that I can see that is going to replace it, is probably going to be WASM or a binary format blob, or the application code executing entirely on the backend and the frontend streamed like Netflix.
