As a client that is likely true.  However, as the topic of this posting
is opt-in, not default config, perhaps that's the important thing to
discuss.

I see the huge benefit large hosting providers get from this extension.
 As a client, I'd benefit hugely from this perhaps, and my iPhone
experience may be better than ever.

However, there is a privacy concern, and that is what the opt-in
discussion is all about.

I also think this is more wide-spread than just the client side.  The
servers will need to be modified to provide address information as well,
and there is no way to do this in AXFR without special changes to group
by address/netmask and add OPT records to AXFR.

I suspect this will affect interop, and no mention of how to tag this
additional data, signal a slave can handle it, nor what happens when a
slave does not handle it is mentioned in the draft.
