The problem is that you rely on the end host to make decisions about which address to use etc. The router can only influence those decisions (by choosing which networks to advertise) rather than force them. This might be good enough for failover (though failover is likely to be slower than doing it on the router) but isn't going to work at all for the type of load-balancing that many people currently do across multiple ISP connections (often built-in to small/home office routers, and like the example in faq/pf/pools.html).
