An alternate approach - involving virtually aggregating prefixes with the same next-hop and passing said traffic via some tunnelling mechanism is currently being progressed through the IETF IDR/GROW working groups - http://tools.ietf.org/html/draft-ietf-grow-va-01 - My understanding of this draft is that it should give some similar behaviour, however, there are still concerns around non-determinism and control-plane scaling. It does, however, seem worth noting that this approach isn't something that's been wholly abandoned.
