Instead of handling this in the bindings layer, have you considered doing these checks in the StorageArea impls?

Notice how ::setItem() is done with the ec out param being plumbed down to area. Maybe consistently do the same for all of these methods. A benefit would be not  checking 'canAccess' twice in the chromium port on each query. When measuring perf times in the past, the cost of the canAccess call was actually a pretty significant taker of time.
