I think some of the use cases require that code running in Window
objects can access the same storage area though. Consider for example
an email web app that uses a WorkerStorage area for to store email
data locally (for performance and for offline support), and then uses
a worker to synchronize that with the server.

Here the code running in the Window wants to access the storage in
order to render the emails in the page, and the worker wants to access
it to synchronize with the server.

See my email earlier in this thread. If we change the name from
'clientStorage' to 'workerStorage', while still allowing the main
window to asynchronously get a reference to the storage, then I think
that about matches what you're proposing (and what item 1 is
