Over on another thread of this list we've already been talking about  
the need to get the user's permission before a site can use [more than  
a certain minimum of] local storage. So that implies the user  
expressing a degree of trust in the site, at least enough trust to let  
it use a sliver of her hard disk.

I agree that if an app is just storing a few kbytes of local storage  
without the user's informed consent, that's just the moral equivalent  
of a cookie and ought to be treated as such.

That would be fine. The problem is that this seems to require an API  
change to allow the site to distinguish between "persistent storage  
I'm just using quietly as a cookie", and "persistent storage I want to  
be able to store larger amounts of possibly user-critical data in".
