Yes, top-level await sounds silly. It would freeze the entire app... You couldn't even render a loading progress bar - It would defeat the whole point of loading modules asynchronously.

incorrect. `await` is a reserved word only in async contexts, the UI thread event loop still runs while `await`ing.

If you run an await as a first thing in the top-level, you have nothing in the event loop to run. Await blocks everything after itself, and that is very dangerous if done on the top-level.

In that script, yes. But in JavaScript you can have multiple scripts :)

You mean, you can embed multiple script elements in HTML? Yes. But allowing global await in ES spec means also enabling it in node.

or you could just do `import('a'); import('b');` to load `a` and `b` in parallel
