Jack, My thinking that led to the draft was to change the current ND behavior to require spreading the load between multiple default routers. Currently ND does not require this. I noticed the current ND behavior when I wrote the VRRP for IPV6 draft, that there wasn't any mechanism to that required hosts to use more than one default router, even when several existed.
I talked about round robin because it was very simple and would do a reasonable job spreading the traffic. Other approaches are possible, but more complex. The draft could be changed to allow other load sharing mechanisms as well.
