Distribution of packaged software is fairly well understood. Is there something in particular that we should be describing? I guess we are missing updates.

<WebMob IG Chair hat on> - we are looking to expand on that work over the next year and are hoping to coordinate with the TAG. Hopefully from that we will be able to produce a document for discussion. Permissioning is a complicated topic (obviously!), as it has technical, UX, and digital literacy dimensions (and possibly lots of other things that make it extremely challenging to get right). It's unlikely the W3C can solve permissioning, but the community can at least provide some valuable input into the discussion.

Personally, I'd like us to keep building on the Web security model. Making arbitrary exceptions for packaged apps or changing the security model of the Web will lead to fragmentation in the API surface and centralization of distribution. We've seen this with all packaged app ecosystems that have been built in the last 7 years. 

We are beginning to look at the notion of a "trusted application" as part of the manifest in Web apps for when an user explicitly decides to "install/add-to-homescreen/whatever" a web application. If the application meets some predefined criteria (e.g., served over SSL, has a Service Worker, etc.), this may grant some additional privileges to an application by default (e.g., unrestricted storage, higher priority caching etc.)... but we are still at the "research" stage with that.
