The reason for such a low-level API is to be able to reuse all the  
existing browser infrastructure, so naturally it wouldn't work at all  
outside a browser.

If one wants to target both browsers and non-browsers, I'm confident that  
there will eventually be a manifest format to do that, even if browsers  
don't support that manifest format natively and require JavaScript to get  
the job done.
