Carsten - how do you define efficient and mostly-reliable? With 15.4E
you get something north of 98% reliable subnet-wide multicast with a
single transmission from each routing node. Is that good enough, or is
the very act of flooding the subnet objectionable?
that DAD is necessary,
Ah, good, let's discuss that! If we don't need DAD, we don't need
half of ND.
Leaving things out is always the best way to design things.
However, we wanted to be functionally compatible with ND.

I didn't understand the reasons presented why we need DAD. The last I
remember was "there might be counterfeit nodes that have the same MAC
EUID". That particular argument doesn't make any sense to me, but I may
have missed others that make more sense.
