If there was an extension to say "this feed is updated immediately upon any change to any entry, the entries in this feed are the canonical form of the entries they represent, and here are their ETags", then the client could avoid doing the conditional GET on the entry resource as long as it knows its version of the feed is up-to-date.

Consider:

   <feed>
      <link rel='http://.../containsFullRepresentationEntries' href=''/>
   </feed>

The feed can either point to itself ("I am the full-content feed"), or somewhere else ("the full content feed is over there."). That is why suggested a link relation instead of <f:feature> or <atom:category>.
