I haven't followed changes in the spec recently, but I most certainly
mean the most up to date. Doesn't the browser, if online always? fetch
the manifest file and check:

  1. if there was an error it could be
    - 404/401 or something like that would show up as obvious
    - a parse error, the resource data would still be useful
  2. if it has changed
    - resource data would still be useful
  3. if it was byte-for-byte identical, or 304, or equivalent
    - resource data would still be useful
  4. if offline, uses the manifest
    - manifest data would be useful

So in all of these cases it looks like the best thing to do is show what
we got from the network! In the case of 3 we may have to show the
contents from a cache (like we already do for typical cached resources).
