We don't have enough IPv6 deployment yet and it's good time to make the decision whether Route Optimization should be MUST in MobileIPv6. I think, it makes more sense to have Route Optimization a 'MUST' in MobileIPv6 draft now than in future, when we might have significant backward compatibility problems. -Samita
