As a user, if you've shown me a UI telling me you're asking for permanent storage to store the data I'm using in conjunction with a given app, you'd better never, ever so much as muse about expiring it, no matter how meekly. If you do, and I lose all those captioned kittens I'd been working on but put on the back burner, you can be sure I'll show up at your place to have a discussion about aggressive expiration. What am I missing?

I think we were operating under the assumption that we're going to
avoid involving the user until neccesary. So for example letting the
site store a few MB of data without the user getting involved, and
only once enough storage is wanted by the site, ask the user if this
is ok.

Asking on the first byte written does change things I agree. We'd have
to look into that.
