I'm not sure that rolling them into the root is a good idea, but I can
see good argument and reason to have the contents of in-addr.arpa and
ip6.arpa rolled into .arpa. I see no real benefit in keeping them
separate and, from a signing standpoint, having them divided both
complicates key management and lengthens the chain of trust for no good
reason that I see. Of course, those who have been working with DNSSEC
and/or the reverse address space my see a very good reason that I am
