Pekka - In theory, I agree.  In practice, it's early enough to make a
change before we have extensive deployments and the lack of backward
compatibility only affects a few deployments, where a host requesting
HCB would be satisfied with and ICB response.  So, I don't think
backward compatibility is as important as improving the protocol.
