Letting faceless background processes update themselves without user
consent is not necessarily desirable. I think that they need browser
UI for this, and/or associated HTML configuration pages that could
(among other duties) trigger application cache update.
So in my opinion, this is pretty much a sub-task of defining what UI
is necessary for persistent workers in the browser, not a question of
exposing application cache APIs to them.
