I wouldn't want the spec to require that either. At that high level, I
think it should just state that:
• Local storage may contain important user data and should only be
deleted by direct action of the user.
• The user must be allowed to decide whether code from a particular
security domain is allowed to store persistent data locally.
• The user must be able to see how much disk space each domain is
using, and delete individual apps' storage.
The first item (which is basically already in the spec) allows web-
apps to store user-created content safely.
The second item helps prevent abuse.
The third item helps the user stay in control of her disk (and
provides the 'direct action of the user' mentioned in item 1.)
My suggestion involving the Save As dialog is just to show a feasible
way to implement those requirements on a desktop OS in a way that
makes it fairly clear to the user what's going on.

What I like about using the regular Save As dialog box is that almost
every user has some experience with it, and knows that it means this
app wants to put files on my disk. Naive users tend to just hit Enter
and let everything be saved to a default location, which is fine. (In
OS X, the default collapsed state of the Save panel supports that.)
Users who are savvy with the filesystem know how to navigate to a
different directory if they want, or at least look at where the file's
going to be saved by default.
It also doesn't look like the type of security-nag dialog that people
instinctively OK without reading.
