The 6to4 anycast gateway RFC practically mandates this, and it does
work when you're doing anycast.  But with static routes, you cannot
handle some failure scenarious, and that usually a good reason to stay
away from such setups.  Of course, in the world of real routers, there
might be constraints such lack of memory or processing power to handle
BGP. 8-/
