*Use cases: *This change allows export-from syntax to export module namespace proxies on behalf of other modules. This provides more flexibility when composing modules using the
existing export-from syntax.
Code that previously looked like:
import * as ns from "mod";
export ns;
Can now be directly expressed as:
export * as ns from "mod";
*Secure contexts:* This is a JS language feature and is therefore present in all contexts.
