Web Bundles are still under development, and we (e.g. @littledan) are currently trying to figure out what MVP non-Chromium groups might be interested in implementing. Could y'all write down what you expect a browser to be able to do with a web bundle in order for it to be useful to this API? For example:

• Does the browser need to be able to navigate a top-level page to a bundle?
• Does the browser need to be able to navigate an iframe to a bundle?
• Does the browser need to be able to navigate an iframe to a URL that was preloaded using a bundle?
• Would it be helpful for the fetch that retrieves a bundle to express what's already in the browser's cache, so that only the missing resources are transferred?
  • If so, is it feasible to have the link to the bundle list all of the cacheable resources inside that bundle?

Dan may have more details he wants to draw out.
