Depends; if it's all the DHCP parameters, that's a lot of information to
spam the bus with when possibly nobody will be listening.  Maybe it
doesn't matter because maybe most people DHCP-returned option list isn't
large.

When I really meant with push vs. pull was that currently,
NetworkManager itself has all the D-Bus code to invoke method calls on
named.  That's heavy-pushing, you might almost call it
poking-with-a-telephone-pole.  I don't want to do that anymore, not for
named and not for anything else either.

I'm perfectly fine with pushing out the information in the D-Bus signal.
