At global scope in a script body, in a browser context, it's an error,
as you presumably know, because `document` is already declared.

Yes. That's what I said.

The issue with it being an identifier isn't shadowing. It's that then
it's a binding with a value, and that value can be passed around,
which I suspect isn't okay.

For clarity: To get `module`, either:

1. It's a context-sensitive keyword, and code that's using it needs to
be updated when migrated to a module.

2. It's an identifier, which means its value can be passed around.

All I've said, again, is: I *suspect* that having it be an identifier
is a non-starter. But perhaps you can get support for a
context-sensitive keyword, if people feel it's worth the complexity
for mildly-improved semantics.
