Excellent news. Google mostly does not have their own desktop OS to "protect", so they are probably incentivised to make the browser and the apps running in it feel as "native" as possible, with proper access to important local resources when relevant. Considering how Apple is dragging their feet with service worker and offline support on Safari (where they have a monopoly on iOS), this is probably a good thing overall. Fingers crossed!
