You can see in the ordering of the PRs that I mostly agree with you. I had to be pulled into the looser description by the people implementing Chrome's and Firefox's permission storage systems. That said, I think the variety of existing stores is a good reason not to try to write up a single model that covers all of them.

It'd be fine with me if we revisit this. (Except argh more work. :wink:) If you want to change it, could you start a thread on webappsec so everyone who cares can be involved?
