Apparently Microsoft requested this before in 13168. To be clear, you cannot
rely on the HTTP cache because:

1. It is more likely to go away.
2. Resources used by other pages will not be cached (e.g. help pages).
3. Using a manifest gives you control over complete application including its
expiry time. You also do not have to perform conditional requests to see if any
of the resources has been updated meanwhile.
