In principle that's a possibility - though it provides an opportunity for more failure modes
(got the package, failed to get it's metadata) - and there will be the inevitable
multiple round-trip concerns, though since the headers before the body metadata retrieval
could be concurrent.

Plausible, though I have not looked at Atom in detail.
