I don't disagree at all, but this needs to be a conscious choice and not 
one made by default.  I don't want anyone thinking we accidentally left 
addresses at IANA. If we want to leave addresses at IANA I'm fine with 
that, as long as we consciously chose to do so.

However, the tone of the previous post was that, we don't need this 
policy because we can just make sure that IANA doesn't have any IPv4 
address space, which is not and will not be the case.
