Wouldn't such an "up" link relation beg the question of a link relation to express a nested feed (a al Google's "feedLink" extension -- http://code.google.com/apis/gdata/elements.html#gdFeedLink?). Such a relation expressing a nested feed would be quite useful (a topic which has been explored here a number of times before).
Linking to a feed can be achieved perfectly well using the existing link element (see RFC 4685 for an example).
What Google's feedLink extension provides, that isn't currently achievable with a standard atom:link element, is the ability to embed the linked resource itself inside the entry. Such functionality has many much more applications than just embedding related feeds though. Why not embed a related image, or a related html page?
Either way, whether you want to link to a related feed or you want to embed a related feed, the feedLink extension seems to me a pretty lousy way to go about it.
