   This seems like something that should be proposed to TC39 first, as this directly affects the ECMAScript syntax.

   I have been interested in extending more of the ECMAScript module syntax to namespaces, but that's been fairly low on the list of priorities. If we did that however, you might be able to do something like this:

   import * as a from './a';
   import * as b from './b';
   export namespace mypackage {
     export * from a;
     export * from b;
   }

   If all you're interested in is exporting values, you could also write

   import * as a from './a';
   import * as b from './b';
   
   export const mypackage = { ...a, ...b };

   }

   I have needed and wanted this syntax dozens of times. Specifically, namespace/function/type merging is useful for representing things like a type User, component function User, and namespace User (i.e. User.someFunction).

   It's extremely hard currently to re-export something like User.Profile if Profile exists outside of the namespace definition itself.
