Re: A followup/writeup on our Monday discussions (was Re: Continuing discussion on Polyfills)

The entry page would link to the fallback app, no need for a link in the
manifest or for the browser to be WP-aware.

This wouldn't get in the way of other apps for the following reasons:

   - a WP-aware browser would trigger the "switch to publication mode" or
   "add to publication list" affordances on the entry page (or any other page
   with a link to the manifest)
   - web and native apps (including browser extensions) would only use the
   entry page to detect the link as well, and then they would immediately go
   to the first resource in the default reading order
