Keith is asking us to expect that mail clients will move behind NAT64

seem likely to me.
For that to happen, someone has to say "well, I think that I'll change my
mail server configuration to be more like a spammer" and then a million
more people have to do the same, eventually weakening the spam signal. I
fail to see why the first few thousand people would do any such thing.
It's a case where we can't get there from here, so debating whether "there"
is a good place or not has no connection to reality. Please let's stop this
now.
