Fall-over and next-hop tracking are two distinct features.
With next-hop tracking, you simply invalidate the next-hops there by
invalidating the routes and choosing next-best option.
With fall-over you tear down whole session, this is usually undesirably
large hammer, consider your IGP flap is very short, if you tore down the
iBGP it might take minutes to recover.

But granted, if current version does not support selective next-hop
resolution it seems like significantly better than nothing.
