      Why not use feed paging and use prev-archive to indicate the previous page and keep your "main" feed as the current page.

      Client just polls the current page and if it needs to go further back in time it follows prev-archive links until it finds what it wants.

      You then avoid the problem of links to things that don't exist or updating already archived pages.
