I was being slightly ironic, but also sort of serious, in the sense that the thing you are saying DHCP fails at, that requires additional complexity, is essentially the same problem as needs to be addressed for homenets: how to do routing when there's more than one default router.   Although in a _very limited_ sense this is solved in the single-homed dual-router RA case, the problem as a whole is unsolved.   If it were solved, we would not need VRRP in the dual-router single-home single-failure case.

I'm not saying we should try to solve it here, merely pointing out that the case you are making has wider implications, and that in fact even with RA, your hosts will be happier if you are running VRRP during the outage scenario you describe.
