In a greenfield deployment I would do exactly that. I am also considering
telling future customers that is the only supported way. But a lot of
existing customers have a setup with a switch instead of a router, with
multiple routers or servers directly connected. A few customers even run
VRRP at their end.

I have high hopes for the solution outlined by Krasimir. I will report back
on that as soon as I can get time to test it.
