I definitely agree to your opinion. We should not judge whether an approach
supports incremental deployment just by whether host change is required.
Nowadays, host upgrade is not such a hard work. Moreover, the id/locator
split is not a so urgent demand that required to be deployed within the
coming 3-5 year.

Since there is some possibility and benefit of introducing host change in
solving the routing scalability issue, how about involving some people from
host OS vendor to join this discussion?
