Why? It’s a local application only technology not useful on the broader internet, so why bother to standardize it? Why waste time of the standards bodies?

>> Nat also assumes that noone wants to run their own internet services. While many things like cameras use a remote server to bypass the NAT leading to vendor tiein, things are clearly cleaner if each workstation or other device like a camera can run its own publically accessable services. Note that this does not mean that firewalls cannot be in place to block things that are not intended to be world readable. NAT is NOT a substitute for a firewall.

Actually, I’d suggest the following:
	1.	NAT Is NOT a substitution for a firewall. It might be integral in the firewall in IPv4, but that’s not the same thing.
	2.	Are cameras on the public internet a disaster because it was allowed, or are they a disaster because MFRs were
		able to assume that NAT would protect them from bad engineering and somehow everyone bought into the idea
		that such an assumption and bad engineering was acceptable?
	3.	I’d argue that switching the expectation from “Everything is behind NAT, so it’s OK to be security-careless” to
		“Everything is publicly addressable and might be reachable, therefore security is important” would be very
		good for the industry as a whole, not to mention end users. Yes, there will be some pain points as this
		transition occurs, but the end result is highly desirable.

>> If you want NAT on the networks you manage, go for it.  All the tech bits to make NAT work in IPv6 are there.  Just do not expect the rest of us that would like to get back to the end-to-end model to support your choice, and I am sure some of your users will wish you did not make that choice, because of things they want that may not work in this enviroment.

So you expect everyone else to put in effort to support your choice of technology because you don’t like our choice… Sounds a lot like your reasons earlier claiming we shouldn’t expect v6 to be widely deployed any time soon.

You’ve successfully argued against yourself here. The advantage goes to v6 without NAT because it is further along in deployment than any effort to standardize NATv6 (fortunately).
