You seem to disagree with my statement of "routing may not be adequate."
in the Internet where majority of the hosts with multiple IP addresses.
Do you really believe that there is an adequate support for the routing
issue described below in majority-hosts-with-multiple-ip-addresses
environment?

it's a problem because it's essentially asking the sending host to do
routing in the absence of any routing information.
if multiple addresses are available for a host, the chances are good
that the paths associated with some of those addresses are significantly
better, or worse, than others. with IPv4 multihoming, the routing system
sorts out which path to use. this doesn't work perfectly but at least
the decision is made in light of some information about the nature and
current state of those paths. with IPv6 multihoming, the sending host is
just guessing. it's difficult to believe that this will work well.
