UPnP is a bad idea that (fortunately) doesn't apply to IPv6 anyway.

You don't need UPnP if you'r not doing NAT.

wishful thinking.

you're likely to still have a staeful firewall and in the consumer space
someone is likely to want to punch holes in it.

Yes, SI will still be needed. However, UPnP is, at it's heart a way to allow
arbitrary unauthenticated applications the power to amend your security
policy to their will.  Can you possibly explain any way in which such a
thing is at all superior to no firewall at all?

I would argue that a firewall that can be reconfigured by any applet a user
clicks on (whether they know it or not) is actually less useful than no
firewall because it creates the illusion in the users mind that there is a
firewall protecting them.
